Default Idle issues!!!
I have 1994 cherokee 4.0L that idles poorly when at a stop and when you press on the gas pedal it stumbles at first then goes. Any ideas about what could be causing this?

Clean the IAC and clean and adjust the TPS.

Brake cleaner or carb cleaner will do fine. Just be careful with the pintle on the IAC and don't spray the connector.

If you take the tps out you will see a bullet looking thing , turn that . Thats how you adjust it.

I've always heard that the HO engine TPS was not adjustable?
