My 98 Crown Vic started to Mis fire today. Got a check engine light. I remember reading that the coils start to break down after 100,000 miles. I jigggled the coil caps a little and found that I could get the misfire to stop. I disconnected the battery for 5 minutes to clear the check engine light. Is there a sure way to check these coils rather than replacing them all? They cost about $60.00 each. Each plug has a coil on top of it.
