i am curious as to why my GP GT sounds like it has a supercharger when it accelerates, i only does it during any sort of acceleration never when turning unless my foot is on the gas pedal. i don't believe its the power steering. i asked a guy at the parts store he said it could possibly be the intake manifold gasket cause its plastic. is that a common thing on these engines? i would also like to ask what are common issues with the 3800 i know its a strong engine but everything has small flaws.
