The Geo Metro uses a 1.0L 3 cylinder engine that is very sensitive to faulty spark plugs, spark plug wires, distributor cap, and distributor rotor. When one of these ignition system components fail, the Geo Metro will experience one or more of the following:
-Stalling
-Difficulty starting
-Stuttering with loss of power
-Hesitation at various engine speeds
If these issues are related to the components listed above, changing the damaged component will resolve the issue. Less common possible causes are the ignition coil, alternator, and crankshaft position sensor.
