1995 gmc popping/sputtering

jrcash57 · 12-06-2008, 08:41 AM

I have a 1995 GMC p/u 5.7 Lthat starts popping/sputtering at 2000 rpm. It does not do this when the truck is idling and I rev it up. It does not do it all the time yet, but it is getting more frequent. Doe anyone know what this might be.

I put in a new distributer, wires, fuel filter, plugs and pvc valve and problem still exists. This problem does not show up until I have gone about 25 miles and will not do it sitting still.
Thanks

Sounds like a closed loop problem, A scanner while driving would probably help
