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.
