This is a different approach for me to try and answer my problem. If you want to see what problems I am having see this thread:

What I would like to hear in this thread is what your truck did when the IPR gave out (for those of you who have had an IPR failure, of course). I am not real good at describing symptoms with words, so this may help me narrow down my issue. Thanks!

 

I answered your other thread.

 

Mine died at idle from switching the chip position...

 

Mine died going down the road. No notice but was running rough prior to it. Not noticibly but rougher then it did after I installed the new one.
