I have heard of one fuel injector going out. They are typically very reliable. They are Denso 24.6lb injectors. I got about 30 of them if you find out one is bad.

You can check the connection to the injector with a "NOID" light. These cost a couple of dollars and should be available at any auto parts store.
The noid light plugs into you injector harness, at each injector (one at a time). The light flashes each time the injector would be activated. If the light works, the injector is getting electricity!
Next, take a long screw driver and hold one end at the injector (one at a time), and the other end to your ear. You should hear the injector "clicking" open and closed.
Now you know the injector is getting electricity, and is functioning mechanically. What you do not know is whether the injector is dirty or gunked up.
If you suspect this is the case, you can remove them and take them to be cleaned (or send them out). The cost is about $75 to clean six injectors.
Before you do this try running some top quality injector cleaner through the gas tank. Research this topic for the products recommended.
The last thing you want to know is, are the injectors being supplied electricity at the right time and in the right intervals. If they are not, you should have a "code".
A decent "SCAN Tool" should be able to monitor the injectors in "real time" and tell you the operating time of the injectors in miliseconds. If an injector is not functioning properly the computer should record a "code".
99.9% of the time an injector is not functioning properly because it needs cleaned. They rarely fail. They can, and do fail. But, it is rare.
There are two schools of thought, at least, on whether to replace injectors as a set, or only the problem injector. You decide!
Hope this helps, rangerj

I lost two of them cylinder #2 & #4 at 120MPH not a very pleasent experience.
If you want a factory replacement you cant beat Torrie's prices at www.fordpartsnetwork.com I believe my quote for all 6 were $400.
www.SPMotorsports.com/taurus.html has them used but are cleaned for $200 I believe.
If you want aftermarket all I know of is you have to modify your fuel rail for it to fit.
