Question about 2002 Jeep Grand Cherokee
My engine revs up to 4500 rpms then drops back to normal, how do i fix this problem
I've seen before where the IAC sensor gets dirty. The IAC sensor is located on the top of the throttle body. If you refer to the throttle body as a clock, and picture the egde closest to the front bumper is 6 o'clock then the IAC sensor would be located at 12 o'clock. I think in a 02 GC it should have vaccum lines attached to it, and it's held down by couple of phillp's head screws. (I think) Take it off and clean it with throttle body cleaner until all the black gunk is out of it.
If you are not sure where the throttle body is, find the air filter box under the hood located on the driver's side lower corner. There will be a plastic "tube" going from that box to the top of the engine. Take this tube off and any part that connects to the top of the engine. You will then see the throttle body. It would also be beneficial to clean the throttle body out as well. (It only take a minute and it can only help your gas miliage.) You can find throttle body cleaner at any auto parts store, or Walmart or Target. Let me know if this helps, thanks!
