2001 SC1, hesitating and******** when accelerating. Some of the time when at speed, but mostly only when speeding up. Engine runs fine, seems to be something slipping. Reminds me of a u joint problem on an old truck I had. Not sure what it is on the Saturn.

Do you
have the same problem?

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.
