Strange Tapping
While driving, if I accelerate moderately (anything above 1500rpm) I'm not sure wat the problem could be. I've tried a higher octane fuel, 92 I think. I know there's better but I need all the money I can get. It is not just that the engine is cold. it still does it after driving for an hour. It might be the timing, carbon buildup, or could it do with ignition? I have not tried these yet, but if I'm leaving out any other possibilities please let me know. Thanks
