I have a 2000 GXE with 85,000 miles. The SES light has been coming on for quite some time. Then it will go off for a little while and then come back on. For the most part, it stays on. I use premium gas all the time. It's soooo annoying. Any suggestions would be appreciated.

 

Mine has been on constantly for the past 3 months. Bring it to AutoZone and get the codes pulled. They do it for free. Sometimes it's the O2 Sensor. I think mine has been on just b/c it's "time for service".
