0430 Cel

Glad to see you have a Durametric, now you can really get into troubleshooting the vehicle. I would clear the alarms and see if they come back in a few days, maybe you triggered them when you opened your oil fill cap doing the AOS test?

I've had those same alarms... They went away after I replaced my AOS (it was definitely bad) and then replaced all my O2 sensors (damaged from driving with a bad AOS too long).

I would take Topless suggestion of adding Techron additive to the fuel tank and taking it for a brisk drive.

As an update, the CEL has stayed off for about 70 miles now (I barely drive) and I passed smog today with flying colors. All I did was pour a bottle of techron cleaner, clean the maf sensor, and replace some leaking spark plug tubes. I'm wondering if the oil from my leaking spark plug tubes caused incorrect o2 sensor readings.

Also for some reason, even though my Durametrics still showed that the secondary air system was not ready, I didn't fail any functional tests during the smog check.
