Just picked it up. 597.00 bill for replacing the negative wire to my battery and replacing the shift assembly.

However, as I was driving home I could hear what resembled a fan revving both while accelerating and in idle. When I got home, I popped the hood, turned off the ignition and waiting a couple minutes. When I re-started the car I watched the engine closely. After idling normal for 10-15 seconds the engine, belts, etc. began revving fast so I quickly turned them off. I also felt abnormally hot air from the vents while driving, even though the heat was off and the outside temp was 78 degrees.

Thoughts?

Unfortunately, I may have to return to the same mechanic tomorrow off hopefully an easy fix.
