CHEVY PROBLEM

1997 Chevrolet Truck • V8 •

I have a 97 chevy truck 1500 and when I stop it hesitates and bulks for awhile before going again I replaced a fuel sensor because it wouldnt start cold had no affect. The problem seems to be fuel related. Replace cap rotor wires less than yr ago

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note: If it doesn't apply disregard it and keep testing
