Hello All,
I wanted to jump into this thread because I'm experiencing a dead throttle pedal issue as well. I've replaced the apps with both a Timbo and Wells and no luck. I had Mechman build me a new alternator thinking that I was getting high AC levels, no luck. For some reason, the previous owner installed a jumper from the #3 pin on the apps to the 23 pin on the ECM - orange/black wire (data link/fuel inj) . I'm not following this logic.
I drive the truck on Friday 150 miles without a problem but, yesterday I had a dead pedal 7 times in 5 miles.
Ready to sell if I cant get it figured out.
Thanks for the help,
Chris
