Well to start off the truck was p-pumped last year! This year we decided to take it back to a vp! Well when i first got it after about a weak the pcm went out and we had to replace that! Then when i got it back it started having dead pedal and threw the apps low voltage code! Then i was hot rodding the truck and took it up to 3800 rpm and the truck started cutting out and threw p0253 and p2054! But it would only do this with the tst on, with it off it would run good up 3800rpm so i thought that the tst was starting to act up so i sent that back to tst! Then the other day while driving up town the tach started jumping all around and idling weird! So i shut the truck off and got p0341 cam sensor and p1690! But when i started the truck up it ran fine! And i havent had a problem since! And also the vp is brandnew from scheid with about 1000 miles on it so im kinda not thinking it has anything to do with that, but i might be wrong! And the truck feels like it has no loss of power!

 

Check grounds and consider shielding the alternator + lead to battery or perhaps a capicator on alt terminal. I"m working on my fix.

 

??? Shielding the alternator, or the lead to the batteries? I didnt know that could cause these problems?
