Any ideas ??? Had the 1/4 turn plug in the engine compartment uncouple. Shutting the car down, Reconnected and now I can't get rid of the noise on the Ref Sync signals and it won't start. I have checked the wiring to both sensors back to the unit and they check good and the sensors do not error out. Just getting noise errors and from time to time an over RPM message ??????????? Thanks Wally :huh: :huh: :huh:
