1994 Chevy G20 5.7 stalling / cutting out
94 Chevy G20 5.7 with TBI cutting out. Started when can
shut down at idle then wouldn't start. About 2hr later van
started but would only run about 10min. Been doing this
ever since but run time is getting shorter. May get 5
minutes when cold before it starts to stumble, climb,
stumble, stall. At idle in park. I have replaced fuel filter, fuel
pump, fuel pump relay, oil pressure switch, EGR, PCM, IAC,
plugs, wires, distro cap, rotor, coil, ICM. I'm stuck and
frustrated. PLEASE help!
Update... new thermostat fixed the issue. Thermostat was not allowing the engine temp sensor to see correct temperature causing computer to lean out fuel delivery when it warmed up and went to closed loop. Last thing I would have expected but she runs great now!
