Your local auto parts store should sell a Ford OBDI digital code reader for around $30, and are worth it.
They come with a nice manual, and it should pay for itself the first time you track down an issue.
Is it MAF? If so, the MAF senor filament can get dirty over time and cause poor performance. A Q-tip and rubbing alcohol do the trick.

does it feel like it's lost power in the low end, high end, or throughout the rpm spectrum?

It feels like on the low end mostly, if I punch it, it will go just fine. Just cruising down the freeway it feels like its lost power.
I'm going to check for vacuum leaks tomorrow and maybe get it ran for codes.

I put a new PCV valve in the truck today, it has never had one on and has 155,000 miles. Then I noticed a cracked up vacuum line. I'm not sure what it's for, but it's about a inch and half long and goes to this unit that's mounted on the passenger side of the throttle body and goes into the throttle body. Anyone know what this thing is? It has a couple of other lines coming off it, I can take a pic if anyone doesn't know what I'm talking about.
Anyway the truck seems to be running better, at least around town it feels like it has some power again. The true test is when I get it on the freeway and see how it does when it's up to speed.
