91 K1500 idle and ac issues
I have a 91 K1500 4x4 350 5.7L that will not idle when at a stop light or stopped period while in gear. While sitting at a stop light i will hold my left foot on brake and right foot giving it a little gas enough to stabilize the engine and it will smoke like a champ while sitting there. Ive changed out the EGR, IAC, and just did the Intake gaskets and still having issues. Idling now will smoke white, in park it will idle between 800-1000rpms, while in gear it will drop to about 500rpms with foot on brake and then will eventually stall out. Ive also ran seafoam through the entire vehicle and nothing. Engine doesnt seem to overheat, idle still jumps. Also once engine is turned off there is some popping coming from inside the engine. Any help would be appreciated.
Also having AC issues for anyone that might have some insight. AC has been charged and when turning the AC on the compressor kicks on for 3 secs then off for 3 secs then so on and so fourth.
