View Full Version : 01 GT is Overaccelerating at stops- Please help!

My '01 Grand AM GT is accelerating pretty darn bad in the mornings when I first fire it up and when I get to a Stop sign it does this too. In the mornings, it will go up to 1500 RPM and then gradually start to go higher and higher. If I turn it off and back on, sometimes it stops accelerating and stays <1000 RPM. Lately, it has been doing this on stops all the way up to 3000 RPM!

Would this be the result of a bad TPS sensor, or is it something else?????

Please help me put a stop to this.

Oh, and by the way, I pump nothing but Premium unleaded in it.

My friends does this all the time and we couldn't figure it out! Bad TPS huh?

My Grand Prix I had did that. I replaced the TPS and it was fixed.
