Hi:

Okay, I need to get some info from you. First, when was the vehicle last tuned up? Were there any symptoms up until the misfire? Is this the only code that has showed up for you?

Let me know so I can determine the best means of attack for this issue.

The ford was last tuned/up about (18months ago). And
has been running fine until now. The check engine light
came on while at the smog check station.I just need to
know how to approach the repair.I have switched #6
coil with # 5 coil, this made the check engine light go
away but I am sure it is only temporary. Your thoughts
please.

Since it went away, it sounds like you may have just had a bad connection. Have you removed the plug to see its condition? It may need replaced and could have been the cause of the problem.

Tell me, is there any misfire now that you switched the coils?

No the check engine light has not reappeared since I
switched #5&6 coils.I will continue to drive the car
for several more miles, and will check #6 spark plug
as you advised. Anything else you can think of would
be appreciated. Thank you Thomas

Thomas:

When you check the spark plug, also check the rubber boot that goes over it. I have seen them go bad and the coil arc through them and cause a miss. The boot is black in color but if there is a spot where it has arced through, it will appear to be gray in color.
