hey guys...
i read a post about cleaning the IPR. i was wondering if this is something i should do for preventative maintainence? also what are/is the symptoms of a bad IPR? i dont have AE to check the cycle, but id like to make sure it is working properly. thanks alot...
IMHO, if your truck is running fine, don't mess with the IPR. When my IPR was acting up, I was getting a surge at low cruising speeds and rougher idle. It seemed to run better under a load, like with the a/c on or accelerating.
