The Crown Vic has issues with the spark plug wires, replace them if the spark plug connector boot looks burned or has holes burned into it. Replace just one wire at a time!! Also do you have a check engine light? You should if your engine has a misfiring cylinder.
The timing on all 96 and newer vehicles is computer controlled so its very rare for one to jump time.One thing bothers me you said you can see spark coming from one of the top of the plug,thats a problem.Check the plug wires because you must have one bad if you can see it.If they are all in bad shape replace them then see how it runs,it might just fix all the problems.
I would visually check for spark at the plugs, to make sure spark is getting to the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
How long since a tune-up? Any applicable trouble codes?
I'm a little confused. You want it to come on?
The check engine light comes on when you have a problem with the engine or drive train. If it hasn't come on, that's a good thing. It's not meant to be a reminder to check oil or anything like that.,, Please clarify? Thanks!
