Well Well we might be getting somewhere, today a mechanic found a short in my wiring harness going to #1 fuel injector which was causing missing that would cause the truck to hesitate and jerk, and also bust up or shut down going high rpm. Now the truck sounds terrible though listen to tail pipe but does run much better. 2 Problems I noticed

#1 When I start my truck in the mourning my idle does not jump up high like it use to during the warm up, but my truck sounds great until it warms up?

#2 When I turn on my AC my idle drops down a bit and never kicks back up, I remember before when I would turn on my AC my idle would raise?

I am hopping these 2 problems are causing the truck not to run right, if not my mechanic wants me to get a new mass air flow since everyone has been screwing around with it!

Thanks for any replies!
