engine running issues.

What would cause a 4.3 v6 to when under heavy throttle stutter ?.. but if you accelerate slow it runs fine ?.. I am assuming fuel filter or bad fuel
prs regulator.. but thought I would ask the guru's here..

stuuters no matter what.. it's almost like no fuel under hard acceleration. If I drive it easy and slow acceleraton it drives fine. But bogs if you hammer it ..I figured it was a fuel filter bought thought I would ask.

You might start by changing fuel filter as it sounds like it might be starving out some. You could do a fuel pressure check too. Is it a TBI or VorTec 4.3 ----------------- TheSnoMan.com

if its a 1995 or newer the problem is going to be your MAF sensor (mass air flow). if its pre 1995 the problem is most likely your tps (throttle position sensor
