Hey i have a ‘88 with a 4.3l non vortec and my truck shuts off at idle when its cold. Once it gets to temp it idles and drives just fine. Anyone know what could be causing this? I replaced my coolant temp sensor, cleaned my throttle body, replaces my iac valve and no luck. Any help? Sorry for my lack of knowledge lol ive been learning how to work on her myself through youtube.
