94' Lesabre rough idle, loss of acceleration...

Call me crazy, but I don't think rain can cause water in a tank unless you are driving around with no gas cap ... it probably came from either running around with a nearly empty tank (allowing condensation to build up in the tank) or getting getting gas from a station with a leaking ground tank.

My dad always said buy gas from the newest station around (new tanks = less contamination) and my uncle taught me to always keep the needle above half ... both pieces of good advice in my view.
