Question about 2003 Chevrolet Avalanche
After driving a few miles I have a significant loss of power. I have changed the plugs (looked good but changed anyway), serviced the air fiter (KN), cleaned the throttle body and MAF sensor. All with no help!!
Sounds like it could be the fuel pump. I had a simular problem with an astro van. does it restart with full power after you shut it off and wait 15-20 minnutes? if if does i would have the fuel pump pressures checked.
