i had to spray pb blaster on my spark plugs to remove them now it is missfiring terrible does it take time for the pb to burn off
When i start the engine I get a noice like a hole in the exhaust system. The RPM jumps to 1K and eventually returns to normal. As the engine warms up the noice level lowers alot. I did pull the manifold heat sheild back as far as I can and started the engine and could not feel any blow-by. The noice seems to be comming from around the manifold area. Any help would be greatly apprecipated.
