throttle position sensor

I can order a TPS online for the Yukon, specially for the XL Denali, according to the parts store. It also has a PPS. It has intermitten stalling during acceleration. Only does it maybe once a week.

autozone specified one too, but when i look on the wiring diagram for your veh, it shows pps but no tps

One year later, the Denali stranded us on the interstate in Indiana. It was a bad fuel pump, overheating and shutting down the engine, until it finally just quit. $950 to fix.
