This morning I went out to start the car, and when I did, I heard what sounded like high pitch squeaking, as if an idler pulley was squealing. The car started, and I only ran it for a couple minutes, but it sounded awful and left a strange smell. So far there aren't any codes that were generated, probably because it didn't run long enough, but I didn't feel like risking it long enough to generate a code before I had a chance to open up the engine covers.

It's making a squealing noise, didn't hold a consistent idle speed, and smelled synthetic. It didn't smell like burning oil, nor did it smell like the usual rich fuel mixture that comes with starting in the cold.

Tonight I'm going to open it up and see if something broke, but it worries me that it's making such a weird smell. It idled and drove fine last night, but left that same smell in the garage. I'll check the usual, but any suggestions as to what else might be causing this?
