Hello, I'm new on here so bear with me, I have a 08 3500 mega cab has DPF delete and egr deletes and I pull a 45 foot goose neck car hauler and on small hills I have the best I can explain a hiccup, I thought is was just at about 1700rpm, but noticed it happens at other rpms as well, the only code I have is a P0111 which is a Intake air temp sensor code, anyone else had this problem and if so what did you do to fix.
Thanks

 

changed your fuel filter latey

 

About 1000 miles ago, but it was doing it before I changed it

 

Do you have an aftermarket air intake?

 

I honestly dont know, i bought the truck like it is. It was a repo!
