weird popping noise/weird shaking when idle

EyeWishXD · Mar 20, 2011

hey guys , my catalytic converter makes rattling noises, and weird popping noises when i accelerate. I recently replaced the cat so the rattling is already gone, but that popping noise is still there every time i accelerate on the freeway ramps, im not trying to be fast, just driving normal speed.

and also, sometimes at a stop my car starts shaking , im thinking that could be my spark plugs or something. but im not sure=/

Sounds like the heat shield around the cat is loose.

could be true, but i got a new cat yesterday, so the rattling noise is already gone. If only i woulda known that before hand i probably shouldnt have changed my cat and wasted money-___- so fml-_-
thanks though. :thumbsup:
