Coworker's 04 Silverado 5.3 in my driveway. New fuel pump leaks around the pump, it has an ABS controller issue, sounds like it wants to die at idle, has P0300 random/multiple misfire, smells like it is running pig rich, and black exhaust puffs from the tailpipe when revved. My project this week!
so the TB EXT and Envoy XL have been called short buses. this GMC must be the long bus. totally de-badged and blacked out tails. husband was driving a lifted chevy 2500 4x4. if bought both new, that's approx $100,000.00 in vehicles
