hello , im new to the forum , i have tried other forums but no luck at all , so here i go , the car is an 88 lo3 sbc it is running super rich . I had a couple codes but took care of them , one was for a coolant temp sensor , another was for a esc module and another for a Idle Air Temp. sensor , now i have no codes and have gone through two o2 sensors , what else can it be , pluggs are gapped at .35 and im running 91 octane , i even advanced the timing to see if it helped , but it just got worse , its as though the ecm wants to stay in warm up mode or something because it runs like this both when the engine is cold or hot . Anny suggestions would greatly be appriciated.
