Barely got it home today pulling my camper all of a sudden throttle is cutting out and spitting and sputtering in low speed low rpm have to play with throttle to get it up to speed once over 50mph holds good have multiple codes when i got home apps sensor low fuel map low water in fuel low all came on at once i have drained fuel and refilled no water in fuel throttle pedal starts to pull then just cuts out to idle spits and sputters from take off untill you get over 40mph then just hickups every once in a while. So where to start ??

 

What are the codes?

 

The codes are P0652, P2127, P2121, P0341

 

The more i mess with it the more codes i get now i have codes P0237, P0652, P2269, P2266, P2127, P2121, P0193, P0341, P0243,

 

p2121,2127,is the throttle position sensor circuit low
p0193, fuel pressure sensor high
p0341, camshaft position sensor performance, bank1 sensor1
p0243, failure of the waste gate contoller
p0237, low boost


Do you have any kind of performance box on it?
Are your batteries fully charged,maybe going bad?

 

Diablo Tuner, K&N air filter and MBRP full exhaust i suspected tuner so i reflashed everything back stock cleared codes took for test drive same issues

 

Also batteries are good i just unhooked and load tested both passed and alternator is charging good as well
