I have spent over $4,000 to find out why my 2008 LS3 Corvette has a P0300 issue (including 3 Chevrolet dealerships). Due to California laws, I cannot legally sell the car with this issue and I was told the statute of limitations is 7 years. Can anyone recommend anyone I can take my car to definitively get a diagnosis of the issue?

The latest GUESS by Chevrolet is I have a sticky valve that causes a mis-fire issue a low RPM's and goes away when the RPM goes higher. This sounds unrealistic because a P0300 is a random mis-fire across all cylinders, not just one valve. Also, the car runs GREAT!

Any help would be appreciated!
