I have a 1989 s10 pickup with aTBI 4.3litre engine. I have a problem with the engine while it is idling, the engine runs slight rough with a miss through the exhaust pipe and runs rich.
If the engine light comes on it runs fine. I change both injectors, throttle position sensor, fuel regulator diaphragm, idle air control valve, and did a major tune up. Cap, rotor, plugs , wires and pcv valve. Can you help?
