I had my truck out today and drove about 10 miles to my dads business. No issues driving there but on the way back i was getting some surging. I turned off my Quad XZT and it had no effect on the surging. Took the truck out of OD and still surged too. It was doing it between 40 and 70 mph, it might have been doing it at lower speeds but I couldn't notice any surging. I checked for codes when i got home and it shows a p0122 and p0500. I checked and the 0122 is for the APPS. Is this just an APPS reset I should do or should I be looking to replace the APPS?
