Engine Performance problem
2002 Chevy Avalanche V8 Two Wheel Drive Automatic 150000 miles
When accelerated truck goes really slow till around 30mph then it accelerates properly. I have to step on gas pedal at around half way so that acceleration can improve, otherwise when stepped all way down it slows down (losing power). It also randomly has its moments where I lightly touch the gas pedal and it over accelerates with a nasty pull when changing gears (rare).
I have used fuel injector treatment and changed the fuel pump, but problem persists.
