stsubs:
All of you have helped me and I am happey for it. But any last words before I take this thing to a shope (DO NOT WANT TO DO NOT WANT TO GIVE UP). But so fare I have put (plugs wires, cap, roter, distributors, coil, fuel filter, and a ICV. Now in my best way to tell all of you what it is still doing. Lopes while idling or idles erratically, also engine stumbles or misses throughout driving speed range, Also when I go to stop 80% of the time it will stall on me. One more thing if I let it idle for a long time the RPM will go low to the pont were it almost stalls but then it jumps back up to 1500. I try to pull the code but can't or just can't do it right and a/zone dose not pull codes on obd1s lol. But for any last help THANKE YOU.
Gastank:
There could be a number of things after the basics. It could be a sensor such as the mass air sensor, or Idle control. The lobe could mean one of those went bad. I would look in a haynes or chiltons, under the troubleshooting section and go from there. It's better to do it yourself and maybe have to replace some parts, but save money none the less. Just my .02
rocket:
did you check all the vacuum lines for leaks? you might have to look hard for one. do you have an automatic? some use vacuum to help shift/tell when to shift. if your jeep fails to down shift upon slowing, the tranny could be bringing the RPMs down as you slow
CnoteTJ:
i agree with gastank and rocket. dont give up yet. i would def. check all vacuum lines for leaks
HOT-ROD:
pcv?
another guess would be the cat(exhaust). if it is old or if you have blockage/loose parts, it will choke out the engine.
