pull each plug wire one at a time and blow out the plug hole with compressed air to remove any water, also blow out the end of the plug wire to remove any water residue there. check each plug wire boot on the outside to see if there is a white powder residue that usually indicates the plug wire is shorting out to the side of the motor. if you want to identify exactly which plug wire is shorting, turn off the engine, pull one plug wire,start the engine. if that is the shorting plug, the car will run the same, if it not the shorted plug, it will run much,much worse. after you identify which plug wire, you can concentrate on fixing it instead of not having a clue as to your next move. if this works, i need a rating boost!!!
