1996 GMC Sonoma Repair Question
1996 GMC Sonoma Hesitates
1996 GMC Sonoma 6 cyl Four Wheel Drive Automatic
My 96 GMC Sonoma hesitates for the first 10 minutes after starting it while the engine is cold. Once it gets thru the warm up it starts and runs fine. Doesn't seem to have the power I think it should have either.
Inspect and test all the following listed below:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
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
