Sorry, I can't agree with your assessment of how the law is used. If you
want to determine partial pressures related to effusion, it can be
calculated.
Permeate is different from effusion in what way?>
The EPA has apparently bought off on the idea in a newsletter:> "Nitrogen inflation systems help maintain tire pressure because nitrogen> does not permeate through tires as readily as air does."
Is this based on the "size" of the molecule? See above....

| Instrument cluster removal Bornfree 21:16:33 |
| | Hello,
I've tried to remove the instrument cluster in my 1999 corolla to
replace some bulbs but there isn't enough extension to get behind the
cluster. I removed all the screws but it seems that the wires
connecting the cluster are too short. Have anyone encountered this
problem and if so are there any suggestions to solve this problem?

| Low-RPM cutout in 1990 Camry V6 Abbottim 20:09:07 |
| | Hey guys. Cruising at 1400-2000 RPM, with very light pressure on the
accelerator pedal (like in rush hour -- you know, typical in LA), the
engine throttle will cut off and on repeatedly, as if the engine is
being fuel starved. The car acts like you've let out the clutch too
fast.
Engine has ~40,000 miles [that MILES, you Canucks and EUnionists].
Recently tuned up.
Any thoughts? Is there a throttle position sensor that needs
adjustment? Other ideas?

| 1987 Toyota Corolla Idle Problem Guest 19:39:36 |
| | I was just playing around with a new CD player trying to put it in and
that, I couldn't get it to work, then when I went to start the car it
was idling fine, I gave it a few revs at the start to get her going
then after that it just cut out.
Now it won't idle at all, I've tried playing with the accelerator
response thinger to see if it was loose or something and the idle
speed, but it doesn't seem to be helping.
Also My 2 front fans aren't working at all. This is problem the reason
why it's not idling.
Any tips or suggestions on what I can do/look for to fix it, before I
have to cart it off to a mechanic?
Thanks.

My Tundra came with the 17" rim package, so the BFG AT's I got were the
only thing that came close to fitting and are at least an inch taller
than the stock tires. I can go look at the sidewall if you need me to.
No clearance issues, and having it sit a little taller looks cool if
nothing else!

There are many things that contribute to drag and make the propulsion system
work harder. Anything that contributes to turbulence will increase drag.
The spoilers and wings on an Indy car are smaller for high speed races than
for road races, where the additional downforce to aid cornering is more
important than reducing drag.
Having the pointy end at the back of the car reduces the turbulence and drag
behind the car. A blunt rear end creates a low pressure area, which sucks
the car backwards, but a vehicle following in the low pressure area doesn't
have to work as hard to move through the low pressure area, the principle
behind drafting in races.
The other area that people often forget about is the undercarriage. A>> shield under the engine compartment will help reduce drag.> Aha, another use for skid plate!

The tailgate on a pickup can act as a large wind brake. Shells and tonneau
covers keep air away from the tailgate and reduce drag, as does lowering or
removing the tailgate or replacing it with a net or mesh.

Excerpts from a Cat's Daily Diary:
Day 683 of my captivity:
My captors continue to taunt me with bizarre little dangling objects.
They dine lavishly on fresh meat, while the other inmates and I are
fed hash or some sort of dry nuggets. Although I make my contempt for
the rations perfectly clear, I nevertheless must eat something in
order to keep up my strength.
The only thing that keeps me going is my dream of escape; in an
attempt to disgust them, I once again vomit on the floor.
Today I decapitated a mouse and dropped its headless body at their
feet. I had hoped this would strike fear into their hearts, since it
clearly demonstrates what I am capable of. However, they merely made
condescending comments about what a "good little hunter" I am. The
audacity!
There was some sort of assembly of their accomplices tonight. I was
placed in solitary confinement for the duration of the event. However,
I could hear the noises and smell the food. I overheard that my
confinement was due to the power of "allergies." I must learn what
this means, and how to use it to my advantage.
Today I was almost successful in an attempt to assassinate one of my
tormentors by weaving around his feet as he was walking. I must try
this again tomorrow -- but at the top of the stairs.
I am convinced that the other prisoners here are flunkies and snitches.
The dog receives special privileges. He is regularly released - and
seems to be more than willing to return. He is obviously retarded!
The bird has got to be an informant. I observe him communicate with
the guards regularly. I am certain that he reports my every move. My
captors have arranged protective custody for him in an elevated cell,
so he is safe....... for now...

I have a 2004 2 wheel manual trans Tacoma.
Only when cold, transmission makes knocking when clutch is released and
only for a few feet (10-20ft)...
I let the engine warm up to make sure that it was not related to cold
weather engine noise and it does not matter.
Perhaps MDT Tech knows the answer.. or anyone else?

| Charlene Blake's B/S Petition Scott in Florida 04:21:51 |
| | Just so new members of the ng can view the B/S Charlene Blake is up
to....
------------------------------------------------------------
To: Toyota Motor Corporation
We, the undersigned petitioners, including former and current Toyota
owners, do hereby give notice to Toyota Motor Corporation, that we are
dissatisfied with the current customer service initiatives for owner
complaints of engine oil sludge and associated secondary problems.
This includes the former "SPA" or "Special Policy Adjustment" (Feb.
2002) as well as the current "CSP" or "Customer Support Program"
(April 2002) for "engine oil gelation." These initiatives do not
restore the original warranty rights of the affected consumers who
continue to be blamed for the problem by this company. In addition,
these initiatives do nothing to help those who had to trade in their
vehicles due to an inability to pay for exorbitant repairs within the
warranty period. While model year vehicles prior to 1997 have had the
same sludge problem, these owners are not helped by the current
program.
Pointing the finger at the owners is unconscionable given that untold
numbers of owners properly maintained their vehicles according to your
recommended maintenance schedule. We, the "Toyota Owners Unite for
Resolution" consumer group are not willing to accept blame for this
very serious engine problem any longer! We would like a formal
retraction of blame immediately. A public statement by Toyota Motor
Corporation is appropriate. We would also like a recall of the
affected engines. If these engines cannot be fixed permanently, we
would like this company to repurchase the affected vehicles once the
problem is formally acknowledged. The owners must be compensated for
the loss of resale value of their vehicles due to this condition. In
addition, all incidental and collateral expenses must be covered.
Nothing less would be fair to the affected owners!
Engine oil sludge development is unacceptable, especially in these
late model vehicles. These engines are not the same after repair. Some
owners with engine replacement have experienced a recurrent sludge
condition. Lack of owner maintenance is not the cause of either the
slow or sudden demise of these engines. Toyota owner engine analyses
reveal adverse changes in the engine's oil condition even with less
than 3,000 miles on the engine's oil. We, the owners, believe there is
a mechanical problem which is contributing to premature wear of these
engines.
Owners are very concerned about the safety of these vehicles. Some
engines are seizing at highway speeds. There are owner reports of
engine compartment fires after the engine throws a rod through the
engine block. Engine failure is unpredictable. Some owners have lost
all traces of engine oil suddenly. Some owners have noted excessive
fuel in the engine's oil and/or glycol-contaminated engine oil. Owners
have lost faith in their vehicles based on these occurrences.
Owners are also very concerned about the emissions control in these
vehicles. Some owners' vehicles are not passing state emissions
testing. Other owners note large volumes of smoke production on cold
startup, while idling, and with acceleration. Oil analyses of some
owners' engine oil reveal low viscosity and high nitration and
oxidation within the manufacturer's recommended oil change interval.
There are also high levels of silicon noted on engine oil analysis.
Owners report oxygen sensor replacements. Others note replacement of
catalytic converters, PCV valves, EGR valves, and other emissions
control components. Some owners have had fuel injection problems prior
to engine oil sludge development.
Here is what the networking owners have discovered to date:
1) Toyota has NOT notified all the affected owners about the "Customer
Support Program" based on a random sample survey of "Toyota Owners
Unite for Resolution" members and associates.
2) Toyota is not honoring the current "Customer Support Program" for
all owners who present with engine oil sludge at Toyota dealerships.
Some dealerships are not providing any information about the program
until asked directly. Even then, owners report vague information.
3) Toyota is charging some owners for sludge inspections or labor when
repairs are made for engine oil sludge. It is denying "Customer
Support Program" coverage for repairs for other owners despite
legitimate qualification for the program.
4) Some owners who purchased "Certified Used Toyotas" from dealerships
have discovered engine oil sludge within one month of ownership. Some
of these owners have been told that they do not qualify for repair
coverage under the
"Customer Support Program" because the owners cannot produce the oil
change receipts.
5) Before the introduction of the SPA or CSP, Toyota asked untold
numbers of owners to pay over $5,000 for new engines. Since the
introduction of the programs, engine replacements are not routinely
done when Toyota pays for the repairs. Repeat sludge problems have
been reported by owners.
6) The NHTSA and the EPA are not formally investigating the affected
vehicles based in part on Toyota's promises to remedy the "engine oil
gelation" situation via the CSP.
7) Toyota technicians/employees have refuted many of the complaint
claims made by Toyota owners on the Internet over a two year+ period.
8) A computer virus originated from a Milwaukee Toyota dealership and
spread throughout an owner list comprised of several hundred
dissatisfied Toyota owners. The most vocal Toyota owners have
experienced a myriad of computer problems since speaking out about
this problem.
9) Toyota executives and/or spokespersons have continued to publicly
claim that there are only a "few vocal owners" in this matter. These
executives state that they are "not aware of engine sludge in cases
where owners have properly maintained their vehicles." These same
representatives say that there are very few cases of engine oil sludge
in the affected engines. They base their claim on another claim that
only 3,200 owners have formally written to the company to notify it
about their problem.
We, the undersigned are shocked and appalled by the actions of Toyota
Motor Corporation. We expected more from our Toyota vehicles given the
daily advertisements describing these vehicles as the "platinum
standard" in quality and reliability. We want what we paid for...a
safe, reliable vehicle that holds its value over time. We don't think
this is asking too much! We want Toyota to do the right thing!
Sincerely,
--
Scott in Florida

| 1989 pickup/ brake problem/ need advice Torque 01:16:56 |
| | recently bought my 1989 toyota pickup from the original owner. its
been well loved. at 217,000 miles, the v6 still runs strong. sadly,
the brakes started acting up. here's the symtoms. excessive pedal
travel, to the floor. no fluid
lost. no blown wheel cylinders. no leaking calipers. for starters, i
bled the entire system twice, including the self proportioning valve
and the master cylinder. after bleeding the brakes worked great. for
about 10 minutes. then failed again. its as if air is entering the
system from somewhere, but no fluid is leaking out. how is this
possible?
and more importantly, is there a way to pin point where air is entering
the system from? i'd like to locate the culprit.

| Tire replacement question (good tread but some "dry rot") Guest 01:16:56 |
| | Hi all,
First off-- thanks to everyone for their recent help on the Code 25 on
my '89 Corolla-- indeed it was the O2 sensor. With your help I was
able to test and replace it myself (got a new Denso part off Ebay for
$22!) and save a lot of money.
Now a tire question-- this is for my wife's 2000 Civic but this would
be a question generalizable to any car-- her car has 44k miles on it
and its original tires. We use the Corolla 80% of the time, and the
Civic mainly for long highway trips, so it sits around a lot and only
gets driven about 4-5k miles a year.
I was checking the tires on the Civic and they still have plenty of
tread left (maybe 5/16") and are wearing evenly. Around the sidewall
of the tires though-- I think it's called the "shoulder", some
superficial circumferential wrinkling/cracking has developed. In other
words, there's multiple superficial circumferential circular lines
going around the sidewall/shoulder area of every tire. By circular, I
mean that the diameter of the circles is just slightly smaller than the
diameter of the tire. By "superficial," I mean maybe 1/16 of an inch
or slightly more. There are no cracks on the actual tread itself. The
tires maintain their PSI fine and only need about 1 lb added per month.
From hunting on the web yesterday I was unable to find definitive information on whether this condition is dangerous or not. "Dry rot"
is the term used to describe this I believe. Does the rubber on the
sidewall/shoulder area contribute much to the structural integrity of
the tire?
We may be moving next year (to what kind of climate I don't know yet)
and I was hoping to wait until next year to replace the tires, since 1.
the climate where we move may favor one type of new tire over another,
2. if we need to sell the car, the buyer might have a certain
preference for what kind of tires he/she wants.
A couple people have told me that tires can always be used until they
lack sufficient tread, but I don't know if this is always the case.
What do you think? Appreciate your input,
John
