Alex when my Vette got caught in the pre-storm flooding one of my sensors for the traction control system must have gotten water in it and the check engine light would come on as it displayed traction control system failure engine power reduced and then the car would only go 22 mph until I pulled over and cleared out all the codes. I would have brought it into the shop but with the hurricane nothing was open and now after drying out for a week all seems to be fine.
I found out how to get into the codes on this page. You may want to do a Google search for your make and model.

How do you know that the electric crew wouldn't be into a tranny and a midget?
