Known Problems

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. 

An engine vacuum leak from the throttle-body base gasket may result in a rough idle and/or stumble on acceleration. If this occurs, replacement of the failed gasket will be necessary.

The brake pedal may pulsate on apply due to warped brake rotors. This condition is commonly caused by uneven lug nut torque. Proper lug nut torque is recommended to try and avoid this concern.

Our technicians tell us these vehicles are sensitive to fuel quality. Using fuel of marginal quality can result in illumination of the Check Engine Light with misfire or oxygen sensor fault codes stored.

The anti-lock brake system (ABS) light may illuminate, especially in hot or humid weather, due to binding in the ABS motor pack. Our technicians tell us that replacement of the motor pack will be necessary to correct this concern.

The spot welds on the hood striker may be misaligned causing the hood not to latch properly. The correction is to install oversize washers under striker mounting bolts to secure the striker.

The dome light may stay on due to a faulty door jamb switch which will require replacement.
