Hi, If your problem truly is carbon buildup in the manifold be prepared to spend around $300 to fix it. It requires a special machine that only dealerships and high end repair shops can afford. I would check with your dealer and see what he wants to charge for the procedure and then shop around for a better deal. Good luck. Ralph

when you replaced the egr valve make sure you clean out the passages that the gasses have to travel through. They can get clogged up. Throttle plate cleaner helps.
