What would cause my ranger to lope?

Exactly like the title said. What would cause my ranger to lope at idle? It is completely stock, and it has never done it before yesterday. I pulled the codes and got 1-engine bank one too lean, 2-engine bank two too lean. I'm sure this has something to do with it, but where should I start? O2 sensors? Thanks.

Even though it only does it some of the time? And the truck still runs perfectly.

Yes, even if it idles at the proper speed. Your "lope" + those codes... IMO = vacuum leak.

Could be a hose or possibly the intake -to- head gaskets.

Yeah, I checked the hose right under the radiator hose, and it has a big crack, and you can hear it hissing. So Ima fix that. Thanks Rich, and everyone else.

LOL. You've been givin' me hell ever since I did that-lol. I hope that didnt cause it. Maybe if I put it in drive and could hear gears grinding, you could blame that. But until then,
