Re: Symptoms of a bad IPR?
Maybe I am having the same problem. While I am sitting at idel my truck starts to idle down like its going to stall then idles back up then levels out sits at normal then down again then back up then to normal.
When it drops it usally below 500 then idles up to around 800-850 then to normal 650-700
