Im kind of going threw the same thing but I know my problem is more of a vacuum or an intake problem. I had the rumble strip problem because of an unbalanced driveline but I only felt it, i didnt hear anything from the engine. The problem I have, which I havent fiqured out is coming from the engine which causes it to buck. Let me know what you find.
