pull codes www.fordfuelinjection.com will show you how. check plug wires making sure they didnt melt onto the header. pull plugs and inspect if its been awhile give it a full tune up an double check the timing should be at 10*btdc with spout connector removed. do you hear any exhaust leaks, spray carb cleaner around the vac lines with the truck running to find vac leaks

"you step on the gas you hear the engine but is moving very slow"

Hmmm....
Did you remove/replace the serpentine belt? I have put on a serpentine belt that was one size too big and the motor sounded ok but gave the illusion that it was rotating slowly because of the pulleys were going slower.

Check your tensioner, it should be around <45 deg angle, not 80-90 deg.

Just something else to look at.
