need some input

[stangman]

hey so yesterday during the nasty storms we had i encountered a flood on my way home from work. well the water wasnt really high so i went thru it. about 15 mins after i noticed my air fuel ratio gauge acting weird. the check engine light came on and it said system too lean and something about air fuel metering. i started the car up this morning and it had a rough idle like it was cammed alil. can anyone tell me as to what is going on and how i can fix this problem?

Dry your air filter out then report back.

im gonna do that and clean my maf since i read up on the maf and when it gets dirty u will get a rough idle

so i cleaned my maf sensor and the rough idle kinda went away. i might need a new maf but i will c how the car will act tonite. idk if the computer needs to get used to a clean maf or not because i never cleaned it before.
