Before I call a local mechanic shop, I thought I would post my problem on here and get an idea of what might be the cause. We have a 2003 GMC Envoy. Normally upon starting the car, the engine will rev high for a few minutes while driving and then it stops and returns to normal. However, this morning I was driving the car and it was revving high continuously. Every time I started from a stop at a light, it would rev up to 2 RPM's and continue higher while the car was just sluggish. I would let off of the gas pedal and it would drop back down and slowly shift but then it would return to making a loud revving sound as I stepped on the gas pedal. There are no lights lite up on the dashboard and everything looks normal except for the loud revving sound and the car being sluggish because of the high revving.
What could this possibly be? I'm afraid to drive the car in fear that it may cause extensive damage. This has not been our year for cars after just sinking $1800 into our Tahoe for repairs.
Ugh! Is this possibly an easy fix and what should I suggest or know when I take it to a repair shop? I don't want them suggesting things that aren't the issue or over charge me.
Thanks in advance for your help with this.
