So I had a 'Check Gas Cap' light come on the other day, and I must have tightened the thing down 100 times afterward. So I pulled out the Predator today and read the engine code that popped up this morning and noted something about the cap being loose/off. So I cleared the code and it hasn't come back yet. But it seems like the previous code I cleared hasn't come back either. Is it something wrong with my car that it won't clear codes by itself? I'm getting the jitterbugs because I'm worried I have a car that's falling apart right before I put 6k Into a KB Supercharger.
