Does anyone have any other ideas what to check on a code nine on b16A in a 88si crx. Just rewired the engine harness. hooked up vtec wires. All wiring is done correctly It has a ls Dis. we swap distributors from a b16 with a b16 distributor works fine. but still code nine. And if the motor is throwing a code with vtec engage? Its hooked up on a switch for now. Its a auto ecu but we swaped a 5spd ecu still the same code. Is there anything else to check or do?
