I recently developed a miss in the number 4 cylinder.I have changed the plugs,and wires.Still has the miss.I have checked the Fuel Injector and the coil pack both are good.The check engine light stays steady at idle but blinks when the car goes over 40mph.Any ideas what else it might be?
1997 Crown Vic with a miss.

you say you checked the coil pack and injector. How did you do it?
The coil pack was checked with a voltmeter and the injector was replaced with a new one.
Inadequate test.
Do you mean a voltmeter or an ohmmeter?
Does this car have multiple coil packs so you can swap 'em around and see if the problem moves.
The coil pack really is suspect here.

Seems it isnt the coil packs or the injector.I have no compression from the #4 Cylinder.All others are reading at 150.
