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?

If the service engine soon light is flashing, it means the computer has detected an engine misfire with the potential of catalytic convertor failure. Don't just tune it up. Bring it somewhere they can read the trouble code. Sometimes it will designate which cylinder is having the problem.
Check engine lights have been used for over 30 years and yet most people do not know what they are used for. The check engine light tells the driver a problem exists with the performance or emissions of the engine. Not the actual engine itself. Anytime something happens that could affect emissions or performance, the light comes on and a trouble code is set in the computer memory. The driver then has to have the computer scanned for those codes to know what component to have checked.
With the engine OFF and the ignition key ON, press the OFF and WARM buttons together on the A/,C conrol panel, hold down for 5 sec and release. read and write down all codes retrieved.Now I would then CLEAR the codes by pressing OFF and HI hold together till "00" and release.Push AUTO to go back to normal screen. Now take the car for 10 mile ride and see if the CHECK ENGINE LIGHT reappears. If so, rereat previous step and let me know.
I can only relate this problem to those similar to Ford F150's,,,on the fords it would be bad grounds from the battery to the frame,and engine,,and from the engine to the Firewall. This would play havoc with the ECM especially when it was damp. So i can only suggest the obvious to me at least. Good luck to you.
I have a car in the shop right now same thing - it is being caused by a misfire. Need a real technition to diagnose the problem (auto zone - advance auto can't diagnose the problem - only read the code)
mine was caused by a failing fuel injector. good luck
