My check engine light came on. The code (at Autozone) said that I need an ignition coil on #3, plugs and wires... I find it strange that it said that I need a specific coil number since it is a coil pack and I can't change just one. So... I have to decide if I really need the ignition coil pack. When I pull the plug wires off (one at a time) they all spark. However, when I remove two of them, the engine does not shake. Could that indicate that the ignition coil pack is working and I need to replace the plugs and wires? Any thoughts?

My 06 Taurus started missing & "bucking" thought that I needed new spark plugs.My local mechanic diagnosed the issue as the coil pack which he replaced. car drove ok for about a month & started with same issue. Had plugs replaced since coil pack was only a few months old..same issue. mechanic thought coil pack was bad, so he replaced it. Same issue. Suggested that I take it to Ford dealer so that it can be tested. Ford said that my fuel rail sensor was bad. I had them replace it & reset my computer as suggested. 2 days later, same issues as before. Returned to Ford only to find out that the coil back was bad. Apparently aftermarket coil packs don't work very well & only 4 plugs will fire. So after paying $400 for a fuel rail sensor, I still need $300 for another freaking coil pack. Very Frustrating!

I had this very same problem, had my plugs, wires and coil pack replaced on my 02 Taurus and the car still ran the same. I had come to find out that my computer system was short circuited and that I need that replaced instead.

I'm going to try to replace just the coil pack this evening. I'll let you know how I make out. UPDATE.... I replaced the ignition coil pack. It took about 5 minutes and seems to be working just fine.

I had the same problem. THe car was bucking and the computer code said it was the ignition coil. THe shop told me that the gap for the spark plugs was too wide (0.65) and the gap should be 0.52-.56, and wanted to replace the plugs due to that. Do you know what your gap was and did you have that problem?

The gap was never a consideration. The problem has not come back since I changed the ignition cool pack. I honestly do not know what gap i have.
