Chevy gmc 4.8 5.3 6.0 reduced engine power p0220 p2135

This video is how fixed the reduced engine condition in my 2005 suburban 2500 6.0. The problem had come back but it was my fault. I did not push the clip on the throttle body on all the way. I pushed it all the way on til it clicked. Have not had the problem in months when it would happen daily. Good luck Update: was replacing water pump on truck the other day and I could see leaves under the fuse box from the side. I removed cover and lifted fuse block and there was a mouse nest inside. It had chewed some wires. Not all the way through. Not causing my issue but concerning. the symptom had come back some time ago. I went back under the hood and wiggled throttle wire harness and truck went into reduced engine power. I checked the connectors where I spliced in new harness and a wire had come out. I soldered all the wires this time. I have not had the issue again. When replacing wireharness always use solder.
