Yeah this first came up after I cleaned and re-oiled my filter in the fall. I cleaned the MAF and cleared the code and it went away until a few days ago. I cleaned the MAF (used a cotton swab on it also and a good amount of dirt ended up on the swab, could be it?), topped off the oil, cleared the code and tested for a vacuum leak. I didn't find a vacuum leak after spraying carb cleaner all over the intake and top of the motor, so I think that's out of the question.
I do see a small exhaust leak where my midpipe and Pypes M80's connect and lead to the catback. I may try to get that straightened out because I read that may be it.
If it comes back on I think I'm just gonna bite the bullet and put new 02 sensors in, I probably need them anway.
