i got a 2012 5.0 with 6inch lift an 35's.. towing two polaris rzrs with my low bow and check engine light comes on.. took it to dealer they test fuel, cam sensor, changed o-ring on sensor, compression test. none of the above fixed the problem. number 3,5,6,7 cylinders are misfiring and all they did was reset my computer and re-calibrate my truck so no engine codes would be on and they called it fixed. picked it up and it is still misfiring but they claim they fixed it. they couldnt tell me or find a reason as to why this is happining this is why they reset everything then drove it an of course it didnt act up on them but when i get home it starts all over again. my buddy has same truck had this same problem 3times on the 4th time he traded it in. anyone have this same problem or heard of any??
thanks

 

Sounds like wiring or faulty ECM.

 

Keep taking it back and document EVERYTHING, do some research on your state's lemon law.

 

so you and your buddy have the exact same issue... but its not widely discussed on here... and this is your first post... ... ...
