CAR STUMBLES WHEN HOT OVER 180 DEGREES

1994 Saturn Sport Coupe • 4 cylinder FWD Manual •

I have a 94 Saturn that runs fine untill it reaches 180 degrees then it stumbles and sputters till it cuts off. When it is cold it is fine.

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.
False air leakage.
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
