About 2 weeks ago I had the apps replace with a timbo sensor (previuosly I had made adjustment to my original apps 4 months ago) because it was showing trouble when shifting betwen 2nd a nd 3rd gear and also prensented the dead pedal symtom while i was driving on the freeway 65mph and when i release the pedal power was back. Any way after i replace the timbo sensor i drive over 1200 w/out any issue at all. suddenly today i was driving on the freeway 65 mhp and felt the loss of power, but my tachometer remain still @1900 rpms, so step on the gas and got power back release it to maintain 65 mph and symptom appear again then went gone. Also I notice trany again is having hard time to decide 2nd or 3rd gear operation. I'm wondering if alternator might have something to do with it, I have read the forum thread that a like from the diodes circuit might drive other systems nuts.

Do you have any idea how many volts your alternator is putting out? I have been having issues with dead pedal as well! Look at thread about apps acting funny! I had broken wires on the back of my alternator! Or your alternator could be going bad! Just a few thoughts!

I have the alternator remove and checked by a tech and found carbon brushes wornout . I replace the carbon brushes 2 days ago and all symptoms are gone,...at least for now:)

Glad to hear that! Kind of thought it might have been your alternator!

Yeah there is a few wiring mods for extra grounds and filter to being added to the PCM. As for experience with it sorry but no I'm a manual truck which it never seems to bother them. But the filter can be purchase at most vendors on the internet.
