Lately it has been happening more and more. When i start my XJ it will Idle at anywhere from 2000-3000 rpm Used to be that I could shut it off and then turn it back on and it would Idle at the proper 900 rpm or so. Now I don't know if it is the turning off and back on or if it is the vehicle starting to warm up. It definatly does it a lot more and worse when the motor is cold.
Would these indicate a TPS? or Maybe a CPS? I am pretty sureif it was teh CPS it would not run at all.
Thanks
