I have a 89 s15 truck with a 92 (4.3) engine. The problem I am having is once in a while the check engine light flashes and when it does the truck starts to sputter and buck as if running out of fuel has no power and you have to feather the gas pedal to keep it going. When it stalls it will start back up but sometimes it will not. And will act like it is out of fuel but the injecters are spraying fuel. It has a new cap and rotor new wires and fuel filter and new fuel lines. Any sugestions?

Since the check engine light was on, have you scaned the computer for troble codes?
