2001 Saturn L300 6 cyl Front Wheel Drive Automatic
On the dashboard, the SERVICE ENGINE SOON light came on last week. I drive under 10 miles a week. I read the handbook, and checked the gas cap, put in the usual type of gas from the same station, but don't know what to look for next.
I live on SS and my brother helps me with repairs. We last put in a new alternator which works fine, and had the battery recharged first. As soon as we connected it, the alarm went off. I drove around to reset the computer, and have had no trouble since.
What can I check out before having to go in to the dealer and pay big bucks?
