1989 k-1500 acceleration problem -

I have a 1989 chevrolet k 1500 4x4 truck with the 4.3 L TBI Engine. When accelerating, the truck seems to stumble/hesitate. It almost feels like the truck is bucking up the road. It will do this if you hit the gas hard, but stops when you let off. Put new plug wires on about 2 months ago. any idea what the problem could be?? |
Could be a lot of things, but I think I'd try and change the fuel
filter first.

where Id go next.

Idled OK, cruised OK, accelerated
OK if I was very gentle. Any normal
acceleration bucked/stumbled badly.
It's probably ignition. Plugs, wires,
distributor cap, rotor. Mine was distributor
cap.
The center tower contact was melted and loose
and the coil wire was fried.
DO NOT use a cap/rotor with aluminum connectors.
Spend the money for brass!

distributer cap & coil wire. When I first start up and 1st mile or so
no problem, then starts stumbling unless real slow with accelerator.
Going to replace coil while I wait for a reply.
