I have a Cadillac Seville STS 2000. SES light started blinking, won't change with WOT. I know its either plugs and wires or coil pack. HOw do you check the coil?

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
