There are a couple of different things that can cause this. The Idle air control motor and the throttle position sensor.
If you can access the trouble codes in the computer it should narrow it down. Its about a 50/50 split on which is more common.
I am getting a new TP sensor..
But can u tell me why my AC Line ( the one containing the expansion valve turned to ice on the outside ) Is that normal ????. Ac is very cold by the way .
Hi, i just came online. Sorry for the wait.
It could be that the expansion valve is sticking. You said that its blowing cold so if the pressures are ok i wouldnt be too concerned about it. If it gets worse you should replace the valve.
I hope that i have provided the information you were seeking. Please use the required rating for me to receive credit for working with you.
