The car: 02 OBW 2.5 (auto) - 145k
At high RPMs my car makes this annoying sound. Its coming from underneath the car. It only happens when I'm really gassing it.
Of course, the good old P0420 CEL has been haunting me ever since I bought the car a year ago, and now its time for me to get my new tags and pass emissions. I had tried all the basic stuff to get rid of the code with no success, so both issues - The CEL and the noise - I suspected were a result of my catalytic converter (its a Walker Replacement converter the previous owner had installed). Ive heard that converters can whistle. I finally took it back to the shop it was done at, and they found it was failing and replaced the cat under warranty. That got rid of the CEL and I should pass emissions with flying colors. However, the sound still persists.
The car runs great, the sound is just annoying. Ill be getting my tranny serviced in a couple weeks. I really hope its not tranny-related, but we'll see. Could it be?
Anyone had a similar problem? Suggestions? Thanks all
