A bad TPS and dirty throttle body can cause low idle, along with a bad oxygen sensor.

Click on th link in my sig and do # 11, and 5.

If you own a Renix Jeep, you'll want to check this out.

Don't waste your money on the knock sensor. Causes no driveability issues.

Do 11 and 5 yet?

Already wasted the $ on the knock sensor so i just put it in anyway along with the o2 sensor. I did #5 and #11 and everything was good, so i disconnected the vac hose from the egr solenoid and it runs perfect with the AC on, it idles a tad high in park but in gear its runs great and doesn't bog down like it was before. I'm guessing it wasn't electrical it was just the engine running weak possibly from a bad egr solenoid? Does that make sense to you?

Could be the problem was the EGR solenoid. 2nd one on the forums this week.

Have you adjusted the engine side of your TPS after cleaning the throttle body and IAC?

Yes I checked both and made sure the wires were not losing contact with each other by back probing on each side of the connectors trans and engine.

Make sure your intake manifold bolts haven't loosened up and be sure the CCV harness is in good shape. Valve cover grommets, piping, hoses, connectors.
