My car runs very rough and wont from a cold start, when it warms up it runs normal Its a 86 305 tpi I changed the tps, cleaned and tried 2 mafs, changed both maf relays. Cleaned fuel injectors. change o sensor, cts sensor, IAC valve! Runs rough, will not idle without help and will stall if i take foot off gas RUNS GOOD WHEN WARMED UP! Restart easily after warm Only thing i didnt try was the ecm!

 

does your car have the THERMAC air cleaner housing? it may be a possibility that the hot or cold air gate may be blocked

 

nope, its tpi
