Throw in a new set of spark plugs and see what happens. Test the plug
wires* and replace them if needed.


*Easy plug wire test: open hood on a dark night with the engine
running, the fuzzy blue glow and arcs around the plug wires is NOT a
good thing!

I had a look at my '97 cherokee 4.0l and can't see how to take no:1
plug out without removing anything else. It looks tight in there
behind the alternator or compressor (I can't remember which).

I have a 4-cylinder 2001 Wrangler that has have *never* gotten more than
15mpg on it's best day. I love the Wrangler, but this little engine is
so underpowered that it works flat-out at highway speeds (which in this
vehicle max-out at about 65-70 on flat ground with no headwind).

My advice to prospective Wrangler owners is to buy the 6-cylinder. The
I-4 is fine for around-town driving, but it is just not enough engine
for this vehicle if you ever plan to use it on the highway.

That's why they make TNT, it'll take out the plug!

Seriously, I drive a Grand Cherokee V8, I traded in my Wagoneer 4.0 for
it some years back and I honestly can't recall where the plugs are on
the six. If it's behind the compressor, it's possible that you can
fool around with extensions and "U" joints to reach it maybe? One
other trick that sometimes works on plugs that are hidden is to use the
old type sheet metal wrench thingy that has the holes in the side where
you stick a screwdriver to turn it, they sometimes fit where sockets
won't.

 It's tight, but they're all accessible w/out removing anything. Pic by bill
is correct.

 I have a 02 Wrangler Sport with the straight 6 and I was only getting about
12.2 mpg on combined city and hwy driving mostly to work. I replaced the air
filter for the first time at 32K miles and now get 14.15 mpg doing the same
type of driving. It is only supposed to get 15-17 anyway, but has never done
that from the day I bought it almost 3 years ago.

 Danny did pass the time by typing:

Depends on the year but either one or the other is in the way. :)­

You need a spark plug socket with the rubber insert removed
and a wobble adapter then a 3" extension.

To remove the boot use a boot puller (T looking doodad) that
hooks around the boot. Fitting the plug back in is easier if you
push a bit of hose over the plug then use that as a handle to start
it in.

 I have had the oil changes and lubes. I have not done the 30K spark plug
replacement yet nor drained the trans. Everything else is done. I also need
to get the tires rotated again.

 That happens to me every time I use one or two particular brands of
gas. They sneak alcohol or ethanol in the gas and I lose 30% or more
mileage.

It is a total rip off by the gas companies. Add a little
environmentally friendly' grain alcohol in there to 'help' farmers and
the air because 'it' burns cleaner. Total BS.

They forget to mention that the gas mileage then goes to crap so they
get an instant 30% boost in their profits and all the dirty air that
extra gas pollutes!

I would also be checking how tight I got the belts. If the belts are
too tight, they will cause a lot of friction wear on the water pump, PS
pump and alternator bearings. This can eat some HP. Enough that I
always made sure mine were adjusted right or even loose when I was
running on a track.

This would be Arco and Beacon?
At 7.5 freeway mpg my Jeepster is not used for general transport, I have
bikes and a 50 MPG diesel car for that.

 Bill showed the right socket. It is the one you can fit a box or open
end wrench on and you take the rubber insert out so it angles on.

Bill's top photo shows it, but there is an angle knuckle in there that
is not needed with the open end wrench.

 if you have a GPS check to see if your speedometer is off...that will affect
your odometer readings and consequently your mileage calculations.

 You still have connection issues so my guess is the computer dropped to
'limp home' mode which will burn a pile of gas.
