Check your Oxygen sensor it's on the header.. your tps needs to calibrated to the right voltage if not it's going to not function properly.. the proper ECU for the engine would be best to run it.. P 74/75 Obd1. OBD1 Pr4 can run it but the B18bs had a difference in compression i believe. needing more fuel and spark and such.. it had different intake manifold also..
