My truck runs great and is super strong whenm cold and when hot
but when wrming up it runs like a turd and is pretty undriveable until
hot. 1991 chev 4x4 350/ auto. It is not flashing any codes at me but
something is wrong. It lurches and coughs until I can rev it up a couple
times. It is like a stuck choke but it's fuel injected??????
Please help me my chevy runs like a ford
