Well if i were in your situation i would start with the very basics. Assuming that you have not done so yet.
Check air filter and replace if necessary (sometimes this makes a difference if its really dirty)
Clean your M.A.F (for your year truck this could really be beneficial as this is what dictates how your fuel to air ratio is and can really bog your engine down if its dirty and most likely is.)
Change your fuel filter (dont know how old it is but if its old enough could prevent a proper flow from getting to your engine)
Change your Spark Plugs for new ones (motorcraft preferred)
Change your oil while your at it if its old. And if you want..you can do a motor oil flush to clean out any gunk that may have formed in your engine.
SEAFOAM!!!! THIS SHIT IS MAGIC!!!! Grab a bottle for 10 bucks and open up the vacuum like from your brake booster and poor that in. Let it get into your engine and eat away at 11 years worth of carbon build up....If you dont know anything about just let me know and i will do a complete write up for you. Its super easy and really does alot for your engine.
All that i have mentioned to this point is very basic maintenance kind of stuff that i would suggest to any one for there car. Very beneficial and can really help get that power back that your missing.
Look through it all and decide what you want to do your self or what ever. If you see that you are getting no where in the end after doing all this dont feel bad about it. At least you did things that had to be done anyway. Let me know whats up.
OH! AND ONE LAST THING!!! If all fails. Your problem could be in the catalytic converter being clogged up. I had a 95 bronco and it had bad loss of power. I did alot of the things mentioned above and it helped it somewhat but still nothing. I then found out the cat was clogged and replaced it and now the engine runs like new.
Well sorry for writing so much i just really get into it lol. Let me know whats up dude.
Ya...Now that i think about it...If your saying that the problem just came out of no where last month it could just be your Catalytic converter that broke at some point.
You can take it to a muffler shop and have them check it or if you want check it your self by getting under the car and banging them with the palm of your hand. Listen and see if you hear like loose rocks. If so then that's your problem.
Once again. Sorry for writing so much. lol.
