my car is being retarded. i just aquired an 88 lx DOHC ZC and only 3 of the cylinders are firing. ive replaced the distributor, spark plugs, spark plug wires, fuel injectors, and its still being retarded. i asked my good friend who is a honda freak and he told me it might be the ecu. the ecu is a pg7. i looked at the indicator light and it kept flashing 19 times. auto tranny solenoid valve? the car is a 5spd. could this be a problem? any help/advice would be great.
