Have 2008 Avalanche, about 48,000 miles, 4wd LT, 5.3L V8.
Only problem was last Jan. had check engine lt, no performance changes; drove home to PA from FL and dealer said had code P0443, reset but said probably would reoccur. Engine light came on once but eventually went out with no problems. Wife drove 3 hours on full tank of gas with no problems. Then next day truck hard to start and keep idle, took to Midas as was closest. Got several codes below, but Mechanic not sure where to start. Left there and am getting towed to dealer on Monday. Any ideas on what to expect when dealer gets the codes on Monday?
P0191 Fuel Rail Pressure Sensor, P2635 Fuel Pump Flow Performance?(I couldn't find this anywhere?), P0171 & P0174 Fuel System Trim too Lean Bank 1 & 2, P0445 Evaporative system Vent Solenoid Malfunction? my table says "Purge Control Valve Shorted", P069E ?, and P0131,0137,0151,and 0157 O2 Sensor Circuit Low volts,

Since you already have an appointment, let me know how it goes at the dealership.

Sorry, forgot to reply: Dealer in DC fixed it under warranty. Was the fuel pump and control module. Not certain which warranty covered it as it had 49328 miles and 3 years old.
