Is this something that I can do myself or is taking it to a shop the only way to have it done?
If I can do it, where can I pick up the materials needed to do the pressure cleaning?
In case my post title is not clear I am talking about the fuel injector cleaner that hooks up to the fuel rail.

I assume you are talking about something similar to Motorvac. Do you have any specific issue you want to address? Otherwise, there is not that much to be gained from this procedure on a Duratec. been there

The car is a 98 svt with 93,000 on it.
Well the issue is that I have been having a stumbling in my car? I took it to ford and they said cylinder 3 plug was shot. It turns out that the store had given me two APP 765's instead of APP 764, so I replaced with the tight ones. It got better and then it went back to the way it was. I took all the plugs out and regapped them and it got better but then back to the way it was.
So the other night I was driving through downtown ATL and I got on it full throttle and I looked in my sideview mirror for some reason and I saw a nice cloud of black smoke (fuel). I think that I had a similar problem a couple of years ago, and it turned out to be a bad injector so I replaced them with green tops (yes they fit with minor work). I do not have any CEL's so that is why I am assuming fuel because spark usually would set of a CEL. Any help would be much appreciated.
My next procedure was going to be the pressurized fuel injector cleaner and berryman's on the UMI/LIM.

The pressurized cleaners (I used Dupont) work great. You need to be careful as they are sold for professional use only for good reason. Not only will they remove paint and cause blindness, but also if you let it get back to the tank (via the fuel return) it will eat away at you gas tank lining. Before trying injector cleaner, remove your coil pack and inspect the condition of the contacts inside the towers. Make sure they are all nice and shinny. Running around with a wrong plug or plug gap can cause the contacts to turn gray and cause misfires. I had to clean my 3 and 4 tower to fix an intermittent 303 code a few weeks ago.

Thanks for the reply. I will definitly check that tonight. So is that stuff only available for the professionals or would I be able to get some. How do you stop it from going back the return line (disconnect maybe)?

Besides the can of cleaner, you will need to also buy the kit that allows you to hook the can up to your car. It is a bit pricy for most consumers, since the kit usually sells for something like $250.00.
If you suspect dirty injectors, it is definitly worth running a can of injector cleaner through the fuel tank first. Use only a high quality cleaner, such as RedLine or Techron (not the cheap Techron, but the $9.00 big bottle).

I will try the techron first then, as that is a lot easier than a 250 dollar kit.
When cleaning the contacts on the coil what have people found to work the best (ie-steel wool, sand paper, small wire brush)? I want to clean of the oxidation but leave as much material as possible.

I used some 220 grit to knock off the heavy stuff and a gentle touch. The contacts are thin so you can sand right through them. I finished with some 600 grit. Never use steel wool on electrical contacts. You can wrap the SP around a wood dowel to make it easier to reach the bottom of the contact.

Poor Man's Pressurized Fuel Injector Cleaning:
Normal disclaimers apply (take your own chances; your mileage may vary), but it has helped me.
I thought of this while changing the fuel filter my '86 Mustang 5.0:
Basically, I filled the new fuel filter with fuel injector cleaner (Berryman's is my favorite for this). The engine will get a short period of pure injector cleaner just after starting.
I used a syringe to fill the filter (so I know I used 120ml of fluid). My filter shipped with covers on each end of the filter; I left one cover on while filling the filter.
Surprisingly, I only spilled a few drops of fluid while installing the full filter. I had to hold my thumb over the end of the filter until pushing the hose on, but it worked pretty well. I then pulled the cover off the other end and repeated the process. A little tricky, but not difficult.
As it turns out, my Mustang had a slightly drippy injector that caused an unstable idle. Running the pure cleaner through the system made an immediate, noticeable difference. This was after adding numerous bottles of various cleaners to the tank; they were simply too diluted by the time they reached the injector to make a difference in my case.
This technique won't solve everyone's problems, but it can make a difference in a bolderline case where adding the cleaner to the tank isn't quite enough to do the trick.

I like that! You are right, it may not fully take the place of a professional cleaning, but it would go a long way toward it. I believe I will try it next time I change the fuel filter.
