97 Wrangler Rough Idle while stopped
Every time I come to a stop my Jeep start running like I have a miss in the engine (2.5). Driving along it runs great. Also if I come to a stop with the AC on it's even worst and my oil pressure drops to zero. Changed plugs, wires, rotor and dist cap, oil changed and cleaned throttle body and IAC. Any more suggestions.

Thanks for any help

Fill in your profile so we know what else you're equipped with! :thumbsup:

1. What oil are you using?
2. Have you checked/changed injectors?
3. Did you check the harness/connections to the IAC?
4. Did you check the harness/connections to the TPS?
5. As previously posted, any codes showing?

I'm getting a code for multiple misfire. I had a friend tell me if could be the speed sensor, since I changed from 29's to 31's. My speedometer is still dead on, and I don't see what that would have to do with anything.

check your wiring harness on the back of the motor, this is a common problem,
the wiring harness rubs and chaffs on the back of the block and valve cover. pull the wire loom off and check the wires for cracks and worn spots. hope this helps

Check for vacuum leaks. Do a search, lots written about it.

Good Luck
