Depending on how long the plug wells were full of water, something may have become corroded (plugs, wires). Not uncommon at all.
Other than that, have it scanned for pending codes and get back to us.

I'm new here, hoping to get some advice...I have a 2004 Focus SE with 117k on it, it's a 2.0 Zetec 4cyl. I bought it from a local dealer and I thought I was getting a decent deal...I've driven it for 60 miles...basically from the lot to my house, in that time it's ate 1/3 a tank of gas, hesitates to go into reverse if it's been running awhile, stutters uncontrollably, and ultimately shuts down if it's been running for more than 10 minutes...I'm thinking it's the Catalytic Converter that's burning everything up...as a side yesterday I found water down in the Plug housing and in and around the plug wires, we dried it out and it ran for awhile, but still sputtered.
Earlier I drove it down to my garage and it barely made it up the hill, as soon as I put it in reverse it started acting like it was low on gas and just sputtered but would move if I gave it just a littttle bit of gas, anything more and it just died out. We're taking it back to the lot tomorrow to hope they'll fix it, but I'm pretty much prepared to replace and pay for it all, I just need to know what I'll have to replace. Or at least general ideas of where to look.
