Hey everybody. New here but not new to Chevy. I have an 06 Silverado 2500HD CCSB 4X4 Duramax, a 2005 Suburban, and a 1988 K5 Blazer. Joined because of the dreaded P2135 code. AGAIN after replacing the TAC module, TPS, and wiring connector. AND several trips to mechanic with no success. Problem returns approx 3 months after clearing code(s) with reduced engine power. and it now shuts the truck off. Found this site from a YouTube video and now looking into what I need to do in order to get this thing RIGHT. All hard parts were replaced by AC delco parts and all wiring soldered and heat shrunk. Any help or articles I need to read to get this thing fixed would be greatly appreciated. Thank you!
