1997 Geo Metro 4 cyl Front Wheel Drive Automatic 114000 miles
The service engine soon light came on on my 97 Metro 4 cylinder and I had it diagnosed.
The message the computer gave was EGR flow insufficiency. I know there is a known problem with that particular problem with the 3 cylinder Metros in that it will eventually cause the exhaust valves to burn up. I had this happen when I had a 3 cylinder Metro. Is this the case with the 4 cylinder engines as well? It should be noted that I am getting better gas mileage than EPA estimated and the car runs quiet and has plenty of power with good throttle response.
