well...i just scanned the codes...here they are...PO133- o2 sensor ckt slow response, PO141 o2 sensor heater circuit malfunction, PO300- misfiring...would these all be results of the maf being wet? possibly because i havent had the o2 sensors shut off since i put my ory in (although this is the first time its happened and ive had the ory on for over a month) or something else?

Scanned the codes again...now its just random misfiring...let the car idle and it threw the code just at idle...any other ideas as I'm beginning to think the maf being wet is out of the question

I'd be willing to bet with 90% certainty that is the cause of the rough idle. But I don't know what year car you have, to tell if it's a vented opti. The codes could be due to the wet opti and you're just not burning all the gas, creating rich exhaust. Alternatively it could be that with the O2, the cooler water shocked it, and killed it.

its the opti most likely...good luck they are fun
I would give it a few days and see if it gets better. Then start lookin at replacing parts. Im sure if water got in the opti its going to take a bit to dry out. Maybe try getting a hair dryer on it LOL.
