Did you install the little flap between the exhaust manifold and exhaust pipe. i.e., E.G.R. heat stove door. They stay closed during warm up but when hot sometimes the spring is worn and lets them flop. I've had the same thing happen and I pulled that little flapper door out of the exhaust by the manifold and it went away. The door is on the passenger side exhaust manifold of GM 305s and 350s from something like 75-85.Last edited by X-ROD; 02-23-2004 at 07:14 PM.
