still cuts out when on 1/4 tank of gas

[dastang2]

hello, 95 still cuts out from 2400 and up rpms when the tank is about 1/4 full of gas. my wife drove it into a bayou and the tank fill with water about 3 weeks ago.i dropped the tank the other day and filled it back up and now it is still cutting out. i am going to change the fuel filter. my question is, does anybody think that the water that is getting into the cylinders with the fuel is screwing my spark plugs up. i want to replace them if i need to, they are not platinums.i already used 2 cans of b12 with 3 gallons of super one time. then i put a can of sea foam too.

i would go though anything that the water came in contact with and change it, such as check injectors, check plugs, did any water get on the electronics?

only the rear end was under, half of the back window was under water so you could see fish swim by.lol
