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).
