studdering and cant find problem

Ok it rained hard as hell the other day and I had to drive my car to work through some deep water. It started studdering when I was easing into the gas and cruesing along. But when I get in it hard it seems to clear up. It finally through some codes and said sensor 1 bank two lean or rich. I cleared the codes and it ran fine for a couple of days then started the same thing again. I am going to check the o2's but is there any other ideas?

likely water hitting the maf.
once it all dries out you will likely be ok.
may want to open things up and dump out water if you find it.

maybe try cleaning the maf?
hopefully it didn't get so wet it damaged it.
I believe you could test the theory by unplugging the maf and the car will fail over to SD mode and then see if it still stutters.

The codes were for low coolantbut I have already fixed that problem. The other one said that
O2 reach or lean, and it said suspect maf or some bs like that.

there you go then. zero in on the maf. try cleaning it. the unplugging it test will let you know right away assuming it stutters all the time right now.

Found the problem!!!!!!!!!!!!!!! The O2 sensor on front passanger side was shot to hell and back. It was loose and wiers were split and worn down to bare wire i have not replaced it yet but as a temporary fix i replaced one of the wires and wrapped the rest in eletrical tape to get buy till i go to the parts store and get a new one.

As soon as i put it back in and took it down the road the light turned off and she ran smooth as silk!!!!!!!!!!!!!!!!
