Your 99 Explorer's service engine light keeps coming on It's always 4 cylinder misfire cold start changed wire and plug what gives?
Think a little deeper. Combustion that fails is a misfire. You have addressed the spark side of it. There is a fuel and compression possible trouble. Try swapping the fuel injector for that cylinder with another and see if the misfire moves to the other cylinder. Compression test the cylinder to see if it is in specs. Try a cylinder leak down test and see if it is losing compression. Perhaps there is a carbon build up on the valves preventing good seating?

You recently had your 2001 Escort serviced the Service Engine Soon light came back on the service tech said there was a misfire on cylinder 3 What do you need to look at to correct the problem Thanks?
Teh service engine light does not mean you need to service the engine. It means that there is a problem. You should have asked the tech that had his hands on the car. Could be a bunch of things from an injector to a spark plug.
Is misfire of a cylinder a drastic problem 1997 Dodge Caravan 6 cylinder had it scanned this was answer to service engine light had spark plugs chged and the wires still same problem light comes on?
These vehicles are known for ECM (computer) problems that cause missfires & other runability problems. Usually if this is a ECM problem the dash works intermittantly (lights, odometer, etc) also. Could also be an injector or another ignition component.

Why is the service engine soon light on in your 1997 thunderbird?
A malfunction with the engines emission control system has been detected and requires service / repair . If the light stays on , and the problem doesn't correct itself after using the vehicle a few times , have it checked out . ( As long as the light isn't blinking , which indicates a engine cylinder misfire , and no other warning lights are on , and your engine temperature and oil pressure are O.K. etc. )
