drive a 2002 chevy express van 1500 The Problem Is In Passing on the Highway.it hesitates and Surges when first Accelerating But Straightens Out & Runs Fine If You accelerate through it.
Replaced Distributer Because top bushing was Bad But Problem is still There.
Any Help Appreciated.



Thanks in Advance.

How many miles on vehicle? How many on fuel pump? Any check engine lights on? How does it idle... catalytic converter or EGR valve. How old is the air filter? Any other issues with the van?
I need a little more info to give more advice.
