hey there, well that's the code im getting, acting funny too, sometimes it just doesn't have any power, then 5 min later it'll be totally normal. from what i can find on the net, it's saying lean on bank 1, dirty mass air flow was one of the causes they say. just clean it up or what? anyone dealt with this? if so how'd you fix? thanks everyone!

Check your rear wires to see if any have melted.

Check your MAF sensor.

It could even be a bad fuel pressure regulator.
