I just got off the highway last nite and I hear a loud whistling (NOT THE TURBO) at the stop light then the car starts idling rough bouncing between 800-1200 RPMs. Then the check engine light comes on. I baby the car home, the temp is normal but the car seems down on power too. Anyone had this problem? Car is a '06 with 25,000 miles.

i'm still new to where everything is piped to under the hood. let us know what it is when u find out
