I have a 92 ford ranger with a 2.3L 4 cyl. It's the one with 8 plugs. The problem I'm having is when your driving its just gutless, and you can feel it missing on one cylinder it feels like. I've done new plugs, wires, coil packs and had the DIS module tested at Napa, they ran the test 3 times and it came back PASS all 3 times. Its not throwing any codes so I have no ideas on what else it could be.
Has anyone had this problem before or know what else could it possibly be? Crank or cam position sensors? O2 sensor? Computer.. I hope not :(? I'm clueless with these new engines, gimme a distributor with points and condenser any day.
I'd like to figure this out, since as it runs right now it takes forever to get up to 55 mph and it sucks down gas like the old V8 I got rid of for this for the reason it sucked down gas.

Replace the Ignition Control Module (ICM), regardless of NAPA's test. Many times, bench testing ICMs is a waste of time--I've seen too many test okay and not work at all.

Instead, I recommend replacing ICMs and coil packs every 120,000 miles or 10 years, whichever comes first. These are problematic components.

Darn.. I guess I go out and spend the $90 for a new ICM, was hoping it would be something a little cheaper to fix but I guess new cars and cheap don't go together. I did try a different one from a wrecking yard, it helped for a month then it started doing the same thing again.
