I ran through a water puddle and my car is not properly accelerating and the on 1999 Pontiac Grand Am

check engine light is flashing, and it is cutting off. What could the problems be?

Asked by for the 1999 Pontiac Grand Am
IF YOU HAVE NOT HAD A GOOD TUNE UP MIGHT BE A GOOD TIME FOR ONE. DON'T KNOW WHAT ENGINE YOU HAVE
L4 OR V6 BUT I WOULD REPLACE IGNITION WIRES AND SPARK PLUGS OR SPARK PLUG BOOTS AND SPARK PLUGS.
SCAN TEST SHOULD REVEAL MISFIREING CYLINDER.
