I had my feul pressure checked and it okay 49.2 psi. Checked vacuum leaks and located nothing. I don't know where to go from here. My truck is running prefectly other then the Flucation with the RPM.
As I stated it I hit a bump the RPM will shot up and then return to normal. Driving on thehighway it shot up and return to normal just to shot up again. Again I lose no engine power.
I have no problem with my transmission and I am not sure this would casue the RPM to shot up.
Therefore, do you have any other suggestion?
Again, the check engine light is not on and have not come on.
