I have been searching on here and found the codes (P0129 and P2106) and what they mean. But it looks like no one has thrown them at the same time. Truck does not want to run now. Some history of the truck (2003 dodge ram 4X4 5.7L) 2 years ago (5,000 miles ago) replaced the throttle body and #4 cylinder exhaust valve spring. I had the cylinder pressure tested and it was on the low side of the specs. today I just finished replacing both front wheel bearings and left CV shaft/joint. Any ideas would be much appreciated.
code P2106 is Throttle Actuator Control System - Forced Limited Power
code P0129 is barometric pressure

Thanks,

Aaron

 

You have find out what caused your truck to throw those 2 codes because I'm having the exact same problem and I cannot figure it out
