As of late every time the car is under load for a bit or if i gun it, for example once i come off the freeway, the car developed a rattle when ilding. Tapping the pedal a tad makes it go away once revs are even a tiny bit higher.
I can replicate the rattle by putting it in reverse under a bit of load. For example if rear wheels are choked with something like one of them shopping centre car park concrete barrier things.
I suspect and my mate thinks so as well its something to do with the exhaust rattling somewhere when heated up and metal expands once EGT's rise. Pissing down here most of day couldnt get under car.
Once again it only happens if the cars been pushed a bit and egts are up. Thats what i think anyway.
Anyone had anything like this?
