My service engine light has been on for months now but the car yields no obvious problems. When I accelerate on the highway, the light begins to flash.... I took it to an auto parts store where they read off some codes but didn't give them to me and turned the service engine light off. The light has appeared on again and I don't have a owner's manual to know what the codes mean so what should I do?
Take it to a service shop if the light flashes there is a real problem

I have a 2000 pontiac grand am gt. I bought the car in july of 08 and 2 weeks after i bought it the service engine light came on and has been on ever sense. But the car seems to be running fight i have seen no problems with it being on. could that be from. well the guy i bought it from told me there was one light still on the dash that was on and it wouldnt pass inspection till it was off. so he took it to the a dealer and they put a brand new battery in it and it shut off. well after it passed insepction the guy took the new battery out and put the old one back it and that light has been on ever sense. Could that be why it is on? something to do with the battery.
