Likely it's a loose heat shield with the exhaust system -- from the header on back to the muffler.
Are you able to give more detail? Can you park the car, let it idle, and listen from the outside?

I'm not getting a CEL, and according to my scangauge, everything is normal, except the intake air temp. It read a intake air temp of 99F on a 50F day. I'm not running a WAI or grille block. Any ideas or suggestions of things to look at would be great. Thanks. |
