ok i got a 97 civic dx with a ls swap and it has the ex vtec wireharness and obd2 to obd1 coversion harness to a chipped po6. ok the problem im having is keeping it running i can start it up and it will idle high for a min then itll die down to where it wants to die and i try to give it gas and itll start crackling and die but if i just feather the gas i can keep it running and itll let you rev it up for a minute then it dies out again. it ran fine be4 i changed these part. i changed from a dx harness to a ex harness and had to extend plugs and change plugfor the iat and i had to change out tb cause my tps broke and installed a throttle body of a f22. ive tried changing ecu to just a stock po6 and still does it and im clueless so please help thanks if need any more info let me know ill answer the best i can
