Try to check the battery maybe your battery is over use or you need to replace the battery or check your alternator and check the fuse of the car.

o2 sensors will put your check-engine-light on. it is attached to the exhaust (closest to the motor)and rusts-out sometimes. you could try to fix it by buying the o2 sensor and use a socket-set to see if it loosens. i 'm not a mechanic but have had the issue, in the past, with the jetta II's and a 1997.the guys at vw dealers are great with info, if your a hands-on kinda guy/girl.

A flashing check engine light is a critical indicator. That usually means that something went wrong that will damage the emission control system... and that is usually an ignition issue. First off, the OEM plug your car calls for is an NGK irridium... NOT BOSCH and not anything with more than 1 prong. Those NGKs are like 2 bucks and they are the proper plug. Make sure you have these plugs and make sure they are gapped to .028. Next, my suggestion is put all the new stuff on again. Drive it to autozone and have them delete all the codes. Drive it around until the check engine light comes on again, then immediately go back and read the codes. The ECU is smart enough to know which cylinder is misfiring. On these cars, I think they have three banks of two... meaning one "coil" inside the coil pack operates two of the cylinders. So if you get multiple misfires, it's the coil. If you get one misfire it's probably an individual plug wire or plug. Good luck.

With a volt meter,check for positive 12V on the coil.

Check alarm for ignition and/or start cut off.
Bad relay on alarm cut off (Bosch type relay)

I agree with bs77bird, I would also try running some sea foam in the gas tank and in the crank case oil. I swear by that stuff!! you can get it at any local auto zone try this link for a visual reference http://cgi.ebay.com/ebaymotors/Sea-Foam-Motor-Treatment_W0QQitemZ170411821067QQcmdZViewItemQQptZLH_DefaultDomain_100?hash=item27ad56080b
