My engine's been running pretty bad for about a couple weeks. I went ahead and changed the spark plugs (V-8, 5.4L) which by itself was a horrible job. That didn't fix it. I had someone read out the codes and got three cylinder miss fires. 1, 6 and 7. My next guess is the coil-plugs, but I want to find out if its possible for 3 to go out at the same time, or if that is too much of a conicidence. I know I can test those, and number 1 wouldn't be too bad to get to, but I wanted to see if anyone else had some ideas first.

Thanks

Ford said the problem is my fuel pump. The funny thing is, i just replaced it a year ago. They are going to exchange it for free, but we'll see what happens. I'll keep you all posted.
