Bad price if you can do the work yourself. The coil is $50 from Auto Zone. I just bought all 8 on Ebay for $87 shipped. I haven't installed them yet, I'll keep you posted.

Do you own a Ford ? If so , do you know what motor you have. Some have CP's while others have COP systems. You haven't fill in your info. The "profile" part of registering that you blew off. Makes it hard to help you when you cut corners. If you don't have the enough courtesy to at least fill the stuff in, then why ask for help?

408 posts and you still say f^ck that? - Well, yea, same to yuh -Good Luck.

Look at my post - upper right hand corner, just fill it in once and you'll never have to again. Not personal info, just your truck and engine size; there's no forgetting that way. Then it's always there with each post.

You need help with that ? Just say the word.

Anyway, you have a bad coil on 6. #6 is a 10-15 minute job to change.

What dabigguy said is absolutely correct btw. - Quick fix is to grab a coil from auto-zone and install it yourself. #6 is easy.

Global Automotive coils are good and cheap, but you'll have to wait 3 days for them to arrive.

I suggest doing them all, but it's a more detailed and time consuming job.

As for removing the all plugs and COPs you need to do a search here and make a decision for yourself.
The #6 cylinder is under the power steering pump reservoir. Unbolt the reservoir brackets from the intake and move it to the side. Unplug the COP connector and remove the hold down bolt that is a 7mm [I think]. After removing the bolt pull the COP up just like a spark plug wire. You may have to turn it to clear the fuel rail. Remember on installing the new one to use plenty of dielectric grease.

Yea, your right torkum, 7mm for the hold downs. 8mm for the fuel rail. The SVT site has the tools listed I believe - extensions and universals + tap . Tap them all specially if you only have one socket the right size.

I guess our tech articles aren't working on this site

Here's a few others -

How to's

Motorcraft Only Plugs.

BTW -Stop calling them "coil pacs" - That's a totally different system from what you have. You have COP's (Coil over Plug) Dedicated coils. Coil pacs energize multiple cylinders.

You can look up "Matt Adams Spark plug change" online - Google it, that's a good one.

Yea go with these - http://cgi.ebay.com/ebaymotors/NEW-I...mZ160267162537

I would go w/Motorcraft "Fine wire" plugs - I think there SP479's. You can get type 3 injectors on ebay pretty cheap. "Bosch 19 lb Type 3 injectors" Those are injectors for these trucks.

Let us know before you install - we will take you thru it , cover all the bases.

Change your fuel filter every 15,000 miles or so agter you do all this. You'll prolly need a fuel pump before you hit 100,000 miles. Mine went @ 90,000 and I changed the filter often.
