Engine Mechanical problem
1993 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic 120000 miles
When I get up to about 50 mph the check engine light comes on. When I slow down from the 50mph the car stalls. It will start right up again. The plugs and wires are about 1 yr old. I have changed the air filter. It has a new catalytic converter and new exhaust from the converter to the tail pipe. Help!
