I have a 2002 Mazda Protege LX. Went through a medium size puddle after a flash flood. Car hesitated but did not stall. Several hours after I got home, started car and check engine light came on. I took the car for a drive and it stalled three times. What can I do?

 

Do you have a cold air intake? Is it blowing white smoke?
The 1st thing I'd probably do is pop the spark plugs out and have a look.
