SC Thunderbird
the car is a Thunderbird SC 1992 with 30000 miles on it
when the car is cold and until it gets a little bit warm the engine runs fine even at full boost (9-10 psi) by the time the engine is fully warm and at operating temperature, whenever the engine is reved there is load and there is boost, the engine knocks badly if thhere is no load, or boost, it doesn't knock there is no check engine code, spark plugs are the right ones it looks like the timming is too much for some reason all the OTC tests were run with no errors the DIS module , spark plugs, fuel pump, fuel filter, cam sensors were replaced and the injectors were cleaned. i would appreciate any help. |

What octane fuel are you running? Your engine has a knock sensor, which could be bad. Have you run a KOER self test?

Sounds like you are running 87 octane in that sc'd motor. Try running 92-94 octane.
