  1. I have a 91 mustang lx an the check engine light is on I plugged it in an it comes up multiple mis-fire so I replaced plugs,wires,coils at its still mis-firing wat else can I do to fix the problem any suggestions please let me know
  2. Get the ICM (ignition control module) checked out. It's mounted on the side of the intake manifold. It's got a plug on the top and bottom and autozone or whatever should be able to check it out to see if it is any good.
  3. I'm look into that today I'll let u no if that's the problem or not appreciate it
