| Rattle Under Car Hi,
I have a 1992 STS. When I first start up the car, a rattle starts from under the car around the CAT area. When accelerating, it seems to rattle until I reach about 2-2.5k RPMs, then it goes away. When I stop again, it rattles again. It is worse when the engine is cold and when it is cold outside. Any ideas of what this could be? I'm guessing it might be a loose heat shield or a destroyed CAT.
Thanks,
Aaron |
