High Idle Issues
Hey guys! I purchased my Cobalt SS SC about 2 weeks ago. I had to fix a few things so I had not got to drive it a whole lot. One thing that I have noticed is that it seems to idle high. It wants to idle around 900rpms when warm which I feel is high. Driving back and forth to work I've noticed that if you throw the car in neutral and coast to a stop, the idle will hang around 1800rpm until you almost come to a complete stop. You will be coasting up by the cars at the stop light and as you almost come to a complete stop, it will drop down to around 900rpm. I haven't hooked my scanner up to it to monitor TPS to see if the TPS sensor in the throttle body is screwed up or not. Any thoughts?
