Hesitation

Elvin Rambaran 5 June 2006 07:29:57
 Hi all. I'm new to Beetles, so I wonder if you could assist me. I have a
1972 Beetle (South African Edition) that starts and idles great. However, if
the car is driven, it reaches about 2500 to 3000 rpm without problems and
then seems to cut out or stutter. You can't get above 70km/h in fourth gear.
I suspect that it is a carburettor problem. Are there perhaps two circuits -
one for low revs and one for high revs? The strange thing about this problem
is that if the car is in neutral and I accelerate, I cannot hear the car
hesistating. I haven't dismatled the carb, but have used one of those liquid
carb cleaners that you buy from spares shops. No luck. Any comments/ideas
would be greatly appreciated.

Regards,
Elvin

Start with the basics
Fuel Filter
Air Filter
Did you check the ign points, distributor cap & rotor?
and those Intake Manifold boots for any leaks?
Valve adjustment
Fuel Pump fuel pressure
Maybe a weak ign coil or bad spark plugs or wires

good luck!

later,

That sounds to me like fuel starvation. Not enough flow of fuel
from the tank.

Could be a clogged (in-line) filter, or clogged mesh screen in the
tank outlet fitting, or screen inside the fuel pump, or a defective
pump.

One test:
Remove the fuel hose from the carb.
Extend the hose into a petrol can.
Run the engine (it will run for 30 seconds or so) and watch the
flow rate from the hose. The spec is 400cc per minute, but if
you only get a dribble then there is a flow problem.

 Hello Everyone,

I own a 98 Wrangler 6 cyl with stock fuel injection.

The catalytic converter was just replaced and I'm experiencing
hesitation while driving. It happens most often when the car is still
warming up but other times as well.

The hesitation occurred before and after the the cat was replaced.

Any suggestions?

Thanks,
Dave

 Low RPM and cracking the throttle is when the spark plug see it's
high compression, and most likely to fail.

 Hi ramva,

I've been tinkering with my bug for a while to get a smooth acceleration.
When gaining speed i feel a lack of power, and higher in the revs it seems
like the the engine can't keep pace (like it won't get enough fuel).

It started when i changed the stock fuel pump with a brasilian one. Because
of a leak in the filter screen i used a sealant to stop the leak. (not
knowing the fuel would solve the sealant, the stock fuel pump got blocked)

First i played with the valves; tighter... looser...
Then adjusted the timing... Dwell... Points... All good, ...on idle!!

Friday i noticed that when accelerating out of a turn or roundabout for that
matter the car almost stalled. I was driving for my sister in law's wedding
so it was pretty bumpy for my passengers. (and nerve wrecking for me!) What
could this be? Just simply a dirty carb? I haven't changed the sparkplugs
jet, could that be a possibility too?

Any help is appreciated because in february (still a long time to go) it is
gonna be my wedding car and i do want a smooth drive

Sorry, forgot to mention.
34 HP industrial engine ('63?) Euro specifications (Swedisch engine)
So more or less stock

Stalling in the turn may be a clue. To me, that suggests
the carb is running very lean (power circuit, not the idle).
This might be caused by dirt/sealant in the Mian jet.
It can also be caused by the float valve maintaining too
low a level of fuel in the bowl.

I think I would begin by taking the carb apart and
blowing the jets/passages out with compressed air.

Thanks Jim.
I was hoping it would be something (simple) like that, but could not put a
finger on it.

Thanks again and i'll let you know what comes out (busy right now)

Hey Jim,

I cleaned out the carb today, lined up the main jet carrier (lining up the
hole of the main jet carrier with the hole in the carb housing by turning
the carrier ccw)
Tightened the solenoid (was hand tight) and re-installed the lot.
When putting back the carb on the inlet manifold i noticed the solenoid was
sitting on the generator. Is this a problem? Anyhow, the car drove perfect
after cleaning the lot but after another drive the lack of power was back as
never before!

It even backfires when accelerating (80km in third, hughe lack of power at
higher revs) бnd decellerating.
There is a little leak in the excaust due to a bad seal and clamb. This is
from day one though and it ran perfect before so i don't think this is the
reason...

The latest thing i have done is loosned the valves a little (0,02mm slith
through easily)

Is my problem still fuel related or will re-adjust the valves, changing the
plugs do the trick? Or is it wondering in the dark?
I must say it dнd run fine for about a half an hour, so it sounds like i'm
in the right direction....

Cheers
Roger

If it ran for half hour, you must have solved the problem
and then something happened. Same thing happened or different
"thing"?

Could be yet another lump of dirt got stuck in the carb.

Put 2 gaskets under the carb to raise it up a bit so the
solenoid has room.

I think I would blow the carb out again as the first step.

Ok, thanks for the (speedy) advise.:-)­
I have a half day off on friday so i'll do it then, when i'm at it, i'll
change the plugs and do the valves again, a little tighter though (massive
backfire related?).

Thanx,

I'm sorry to butt into this conversation (yea right, haha!)

But did you make a typo there, perhaps you meant to say 0.20mm?

The proper clearance for aluminum pushrods in a fairly stock engine is
0.15 not 0.015 !!!

0.015 would go to ZERO when the engine warms up, and you would get leaks.

It works the other way with steel pushrods, then the clearance gets
bigger as the wngine gets hotter. It's because they have different
thermal expansion.

Yes you are right, i meant 0.20mm.
I think they are too lose now. will make a tight 0.20mm next friday
Thanks for the correction.

 My 95 Civic with the 1.6 VTEC engine (195,000 miles)has been experiencing
some intermittent hesitation. This is most noticable on warm days. It
seems to have started about the same time as the change in fuel that now
includes alcohol. About the same time I had also checked and cleaned a
well operating PCV valve.
I have no ECU codes. The idle speed sometimes drops a bit when the engine
is very warm. The plugs, dist cap and rotor are almost new, The fuel
filter is going to be changed again. I have reviewed many ideas on the
search feature. I'm not sure if this car has an EGR system of some sort?
My manual only makes reference to the 1.5 engine having an EGR system.
Thanks in advance for any ideas or assistance.

I assume the new plugs, cap and rotor are OEM?
Add comment
Duckbill 4 June 2006 05:15:52 permanent link ]
 Yes, OEM. I should also comment that I noticed the
PCV hoses were a bit brittle and I used some soft Permatex to ensure a
good seal after cleaning the valve. I'm planing on replacing the upper
and lower PCV hoses as well as the valve. Prior to sealing the PCV hoses,
the hesitation seemed to be worse.

Random hesitation on an old car is usually caused by a failing oxygen
sensor. It becomes covered by molten ash with age. Eventually it's too
slow for the emissions feedback loop so you'll get surging.

 Do check the level in the cooling system reservoir; top off
per the manual; purge of air. Forty minutes may be required
before the fan comes on twice during the purge procedure.
(Have you had any work done on the cooling system recently?)
Temperature sensors, inter alia, not fully submerged in
coolant will send erroneous signals to the computer, etc.

The oxygen sensor should be eliminated as a cause of this.
The 92-95 Civics, for one, are supposed to set a code for
it. Still, I'd keep it in mind.

After 1992, only the Civic VX came with an EGR system,
according to my Chilton's manual.

Air filter has been changed recently, right?

 Oxygen sensor was replaced around 6 months ago because of a bad heater.
Water pump, timing belt replaced a month before the problem started.
Timing is right on the money. Just filled up with premium and added some
fuel system cleaner (Chevron with Techron). I have also purged the
cooling system, but I will check it again. Thanks for all the ideas!

Was the purge done before or after the water pump change?

Just want to cover all bases.

 Thanks Elle....Air filter has less than 10,000 miles and looks good.
Replaced fuel filter today. Some nasty looking muddy stuff came out the
gas tank side to my surprise. It had 50,000 miles on it. Did the 30 min
purge of the cooling system today with the nose of the car up on maint.
ramps. Tweaked the idle up 1/16 of a turn. I'm going to test drive it
now and see what happens. Thanks again to all for the ideas.

I'd be surprised, too.

Get some bad gas somewhere?

Are the fuel lines maybe clogged with corrosive debris?

Try not driving the car all the way until the fuel gage is
empty. It's said that the fuel pump picks up all the bottom
debris from the fuel tank this way and puts it into the fuel
system. Not good.

I'd also add a bottle of Chevron Techron (~$6 at Wal-Mart)
to a near empty tank, then fill.

Monitor this. Sure sounds like you are on the way to
identifying the exact problem (related to the gunk in the
fuel line).

 The gunk came out of the fuel filter on the input side. Fuel line from the
tank was clean. The problem started occuring right after the big switch to
alcohol in the fuel about a month ago. Service stations had to get the
water and gunk sucked out of their tanks before the new fuel with alcohol
was added because that fuel would let the water at the bottom of the tank
mix with it. Looks like my fuel filter did its job and captured some of
that. Put some Chevron with Techron in my gas tank Saturday.
I'm hopful my hesitation problem is solved! Thanks again.
