where in florida are you?

John: a few thoughts to add to Sin's analysis/suggestions: you probably got your alternator wet, as well as your catalytic converter, which went from super-super hot to ambient (=cold) water temperature in a flash, when you 'hit' the water; and as you know, cats don't like water! :>) Also, if you wind up having to undo your battery, there is a product that takes a 9-voly battery and plugs into your cigarette lighter (costs between $10US and $15 depending on source...IPD has them, as well as 'autosportcatalog': it keeps your radio codes, etc., which you would otherwise have to re-set after a battery dis-co). I know it's a bummer to encounter high water, but unless it's an emergency worth endangering you and your car for, 'the authorities' suggest NOT driving thru high water, and you have just found out, the hard way, one reason why. Let us know how it comes out?--PD

Your engine ingested water. The water caused misfiring. You have probably fouled your plugs, and contaminated your engine oil.

I would disconnect as much of the ignition system as possible, dry, and replace if necessary. REPLACE the plugs, and change the oil.
