P0401 code, lost power ever since
I am knew to the forum and i was hoping you guys could help me out. I have a 06 lbz with the bully dog triple dog and was pulling my camper back home when my engine light came on. I did not have my out look monitor because it had a glitch in the screen and had to be sent back to bully dog(which took for ever) I did not realize the program was set on extreme. The tail pipe started rattling and blowing black smoke when i gave it throttle. When i got home i cleared the p0409 code and ever since the truck is lacking the power it once had. The engine light has not come on again but even my wife can tell the diffrence when she rides in it. What should i do, the truck has 39,000 miles on it. What should i check first?
