'97 5.7 k3500 with 81k on the motor. In the last few weeks it has slowly
grown to have a hesitation, slight lack of power when accelerating.
Almost a bit jerkey like it was mis-firing. This would be true while in
park and reving the motor too.
I had the fuel injectors and pump replaced new about 12 months ago.
Spark plugs, wires and cap too. Exhaust doesn't smell bad. Any thoughts?
Thanks in advance,
