BTW, why are you using 93 octane in a V6? It is of no benefit.

just got the code read P0300. Its a misfire code. that was using my buddys EFI Live tuning module. If I go to an auto parts store can they read it and tell me specifically which cylinder? his efi cant do that. and also my 36k warranty is up. Would this be covered under my 100k powertrain?
