Regarding the gentleman who called into the show today with the car that would go clunk after coming to a stop. (don't recall the type of car he had) It sort of reminds me of what my car will do on occasion. Sometimes after coming to a stop for a few seconds my car's A/C compressor will kick on, kicking up the idle speed of the engine. From time to time I can hear my rear brakes grabbing harder as the car attempts to move forward because of the idle speed increasing. Could be that's what he's hearing also.
