Sunburstcruze

So the other day I'm driving and bing on comes my check engine. Day goes by still on. Got it scanned (can't remember the code for the life of me) but it said bank one is running to lean... So I put in some new iridium platinum plugs. Cleared the code. Day or two goes by and code pops up again. The car physically runs fine. No real gas mileage loss just this damn code.

Any ideas ?

Thanks Jason

bank1 1 sensor 1 or sensor 2? most likely one of ur o2 sensors needs replacing.
