Looking for some help...truck acting wired and DTCs
I was driving around tonight and truck was running fine. Went to accelerate from a stop and the engine light comes on and I have no power while stepping on the gas. It's like the truck is dead, then after a few seconds it tt takes off like normal and the cel goes off. Few miles later, same thing.
When I got home I pulled the codes with my Hypertech programmer and got 3 codes....P0122, P0472 and P1670. Looks like these are exhaust back pressure sensor, Throttle position sensor and something about low voltage. Wondering if I should replace the TPS? Also wondering if the CPS could be the culprit?
Truck is an '03 auto, stock except for the Hypertech.
