Usually, this is caused by the muffler being incorrectly installed or the entire exhaust being miss-aligned. The tail pipe outlet should be at ~7 o'clock when facing it and the tail pipe should be facing slightly down.

Thought I had an engine knock but it is my muffler just knocking the fiberglass. So now my ? is do you think the whole engine may be loose somwhere (like tightening a bolt)because the whole engine seems to shake a little when this happens. Also it only happens at turn off of the Van and at certain times during idleing? |
