Mopar Part Number IAC "surging idle"

[Kunit13]

Just purchased a 1997 TJ 4.0 (3rd jeep). Been about 10 years since I owned my last TJ. I've been chasing a idle surge problem.

The jeep starts easy idles fine right at first then starts to surge, at full warmup idle is fine.
After researching I have replaced IAC valve and the IAT sensor. Idle did get better, but still a little inconsistent. I tried cleaning the TB first before replacing. Unfortunately the IAC that came with the jeep was not a Mopar unit. I replaced with a oriellys part.

I've been searching for a MOPAR part and it looks like they don't make them anymore. Does anyone have a line a on a new part number or a suitable OE replacement?

I also saw that it could be the water temp sensor? My jeep only has the sensor near that thermostat and watching my temp gauge it seems fine (runs about 200-205).

Any other suggestions?

Thanks,

I recently replaced my IAC with a Standard Motor Products from Rock Auto. Seems to work well after the computer "learned" the part. Now runs like the original Mopar part that was in there. I always go with Daily Driver, Standard, Heavy Duty or Performance parts from Rock Auto. Never go with the economy parts. Have always had issues with the economy parts.

BTW - Rock Auto shows it has a MOPAR part. If you are into drinking that Kool-Aid.

Thanks for the link. Looks like no Mopar parts avail. I ended up getting a another IAC from Autozone (Duralast). It seems to be better still a little idle searching. Since my jeep is not a daily Ill need to put some more miles on it.
