I have a 2007 Ford Taurus. I was getting a random misfire, had a tune up. Same code came back and got another tune up. Then they told me it was the coil pack, had that replaced. Now I am getting a random misfire on cylander 3. Any suggestions would be appreicated.
Might be your spark plug. The coil pack he replaced, was it the 1,2,3 or the 4,5,6? Did they clear the codes?
They told me there is only one coil pack. I have had two tune ups in the last year.
Correct, all the coil packs are in one module. I replaced mine with an aftermarket unit from AutoZone and it quickly failed. The real Ford part is only ~$90. Also, you may have a bad plud wire. A replacement set of plug wires is cheap and takes 5 minutes to replace. Try this first. Also, if you had "tune-up", did they replace the spark plugs? Were the correctly gapped, if so? Otherwise, put in new plugs with the new wires...
