Hey guys, just wanted to let everyone know that my issue is now fixed. The plenum was bad and I replaced it, but the real issue was with the up-stream O2 sensor. I replaced that, and no problems since.

Thanks everyone for the help.

 

Cool.

Yeah, the burning oil takes its toll on O2 sensors.

How is your cat? (converter)

 

The cat has been hollowed out for about a year and a half now. So yeah, it went bad awhile ago.

 

Good. Takes care of that potential issue. Should be golden now.
