2008 Ford Taurus X SEL 3.5 with approx 100k new oil change previously the truck ran great; I have replaced cylinder 4 with a new spark plug and switched the cylinder 4 coil pack with the cylinder 5 coil pack. I am still getting a PO304 cylinder 4 misfire detected. I never saw any codes prior to the truck running rough yesterday. I scopped and found; PO351, PO352, PO354, PO304 I cleared the codes and the only one showing now is PO304. I have been searching for manuels and help with diagrams with no success. Any help would be appreciated.

You should be able to find a Haynes or Chilton repair manual from local parts stores. If you're looking for something more along the lines of a Ford Factory Service Manual, you might consider a subscription to Alldatadiy.com. The information they have for modern Fords is directly from the factory service manual. And if you are looking for just a diagram or two related to the ignition system for your Taurus X, send me a Private Message with the request and an e-mail address and I'll send you a PDF or two.

Would you be up for the challenge of moving a couple of fuel injectors around, similar to what you tried with the spark plug and coil pack? Or do you happen to have access to a cylinder leak down tester?

Rod,
I have searched far and wide for the Chilton and Haynes manuels only to be told they don't make them for my vehicle. I have since replaced all of the spark plugs and there is no change. I will check out Alldatadiy.com I payed for the on line RepairSurge and found it was just a great place to park my money. As for moving the fuel injectors I will try I found the wires are very short

Thanks Again for your help Rod,

For a online manual try your local library website, see if they have EBSCO HOST, if so they should have a link called ARRC (Auto Repair Reference Center). It is in the line of a Haynes or Chilton manual.

You could also call the Library and they should be able to tell you if they have it available.
