I have a 98 wrangler 2.5l. It idles rough and stalls out when I come to a stop after it warms up. I replaced the plugs, wires, idle air controller, throttle pos sensor, oil sending sensor, and pcv elbow. just bought this jeep and any help would be great. it has 113,000 miles
 

Have you adjusted the idle speed?
What RPM does it idle at when cold?
 
I was not aware that you could adjust the idle on a fuel injected engine. If you can, any advice on doing so would be great. idles rough when could but around 12oo rpms. thanks
 
You do not adjust the idle speed on a TJ.

I recommend removing the throttle body, all the sensors, and giving the TB a good bench cleaning. Clean the IAC housing and plunger very well.
 
You can't tell by looking at it, I would pull it and remove the IAC sensor and housing. Give it a good bench cleaning with carb cleaner and a toothbrush.
