Bought this a week ago or so, no codes until today.

All of a sudden I got 2 lean codes, 1 for each bank...I cleared them so I guess we'll see if they come back.

Thought I post here and just see what you guys think it might be if it returns (I got a 36,000 mile powertrain warranty, so whatever it is should be covered if it comes back).

I would guess this is probably coincidence, but this happened the 1st time I hooked up my little mower trailer and drug it and the mower around the block in tow haul just to see how that went.

Sounds like someone cleaned the codes before it was sold and they finally popped up. Scummy tactics.

Not really what I think happened, light comes on pretty quickly and didn't come on right after I bought it.

Anyway when I posted I was hoping for some ideas on solutions...as it is I think I'm going to throw some front o2's at it, on my scan tool one of them looked lazy even though there a code for both banks showing up.
