My "Service Engine Soon" indicator light intermittingly goes on, then it'll just turn off. It may stay on for about a week, then the next time I start it, it'll turn off. I've asked around and some say it maybe the PCV or the O2 sensor. Thank you for any help you can give me.

The fault is stored in memory and can be retrieved by using most any generic OBDII scanning device. It is never a good idea to repair things unless you know what is broken first, so dont just throw parts at it until the fault has been extracted and analyzed. Repost if needed.
