I have an 04 Yukon XL 5.3 flex, I have owned for 4 years and up till two days ago has been "fairly" reliable 389k on the clock. Have struggled w various electrical issues over time w this truck. Two days ago the infamous reduced engine power has reared its ugly head 750 in parts later and still have the same issue. Did all the wire inspections and ground connections replaced tac mod throttle plate assembly checked fuses, has 2.5 v to tps 1-2. Tac module performance, tps 1-2 control system failure, throttle plate performance. And a correlation code for tps. Code will clear cold start lasts for about four revs and back to sounding like a f ING tractor chugging and super lean bordering on stall. I am developing a serious hate for this truck. On a fixed income and have zero ideas left. Burn it or dump it are about where I m at. Maybe someone has an idea?
