Hey everyone, I keep having a P0300 code pop up on my interceptor ever since I got 60's and a tune but the cel light has only gone on once so far. Anyone know if I can pass a state inspection with the interceptor throwing the code but the car itself not indicating one?

 

if the interceptor is flagging it so is your computer. not all codes will set the CEL light.

 

^what he said. The computer will still show it if they scan for codes. That code will set the CEL but it has to throw the code to the computer more than once before the light comes on.
