Sound like a loose exhaust. Get it up in the air and check for anything that may be loose.

Sounds like you may have a little back fire when turning engine off,usually means there is and exhaust leak,or blockage in your catilac converter.

Keeping up with the oil changes is a big plus, to be sure of the oil pressure you get it checked with a mechanical gage, half the time just replacing the oil pressure sending unit takes care of it.
