Hi my 2005 chevy equinox is making like a low rattling noise while idling on park.its kind of annoying i just did an inspectiin and passed. If i hit the gas it goes away but while idling it does it what can it be? Please help other than that the car working wonderful. I had just changed all my mount, oil pan gasket, changed oil, did a tune up changed the breaks and ran it thru diagnostic no codes. Don’t know what else to do.
sounds like you disconnected something and forgot to reattach. Retrace your step as if you were going to perform the work again. I assume you removed the motor mounts to change the oil pan gasket. did you unhook the exhaust? It often has a heat shield of thin metal that might product a ‘rattling’ if not reattached.
