My 94 I6 ZJ is idleing like crap.
I've replaced MAP, TPS, plugs, fuel filter, air filter and thermaostat(195).
When idleing it idles around 400-500, after driving if i stop and leave in gear it idles around 800 if i put it in neutral the idle goes to around 1200-1500. Also my temperature gauge never gets higher than 160ish, my heater blows hot though.

Ideas???

Some folks have pulled the oil pan and cleaned out all the crap in there... Might be pretty time-consuming but I've heard from more than one source that doing that makes high-mileage 4.0s idle like new.

That sounds like an IAC that's dirty or just plain bad.

I'd look towards the IAC as well, them being bad makes or ZJ's run like crap and stall out constantly. I just picked up a new one from autozone, fixed my massive number of problems.

How much did that cost you?
