Hi I have a 1998 ram 1500 4x4 5.9 gas and after replacing the tps and the iac valve I still have an idle at around 1600 rpm other than vacuum leaks is there anything that may cause this issue?
Worn out throttle shaft or stuck iac valve. I would think you would have some vacuum lines that have not been replaced though. Somehow extra air is entering the engine.
