ECU reads it is functioning and gives a corresponding code.No diagnosis as to anything wrong. When installing the timing belt everything as alined TDC with the gear markings . The original timing marks had floated off as the bushing slipped between the harmonic ballancer and timing gear. It was re-marked and timed at this point.
12. The problem is when timed the motor runs fine while sitting.. When driven it runs rough and the timing is thrown off. The timing point seems to float.
If the crank or cam was bad the motor would never run smooth. Even while sitting.
Not necessarily. A bad cam or crank would cause the motor to run rough immediately when the motor is started. I have delt with this condition in the past. Thanks for your input, I need to get another opinion.
