1G CEL O2 Sensor?

[wicked93GS]

ok, heres the deal, my laser has a problem, evidently anyway, the check engine lights comes on, then goes off about 20 seconds later, it continues to do this all the while I'm driving, if it stayed on I would actually think that something might be wrong with the engine, but its so intermittent, I was wondering if you guys think it could be the O2 sensor? what other symptoms should I look for if it is the O2 sensor?

It could be the O2 sensor. But there are a bunch of other possibilties also. Check www.vfaq.com for the procedure for checking codes.
