hey everyone, do yall have problems with your valves rattling like i do? I wonder if I need to run seafoam through her again? Maybe a different gas company? I dunno... See, i normally drive her around real slow, but i just got my computer back from wait4me so I took her for a run or two.. and I couldnt get them to stop rattling... i did about 5 or 6 WOT runs with the same results... could i maybe be mistaking it for pinging? It has 89 octane in there right now and he put the 89 octane tune in... any ideas?
