Sorry you feel that way but the question I answered has no other previous questions about this issue just the one listed here. Unfortunately that would be the first thing to check. If you can check the vacuum at idle if it is at 15" or below, suspect a clogged converter which should give you a code 420 or 430 as you have two on your truck. Most auto parts do this for free. The only other thing to check would be a cam and crank sensor for resistance as sometimes they won't give a code which we have not data for so you need to check against a new one. If high then replace it. Or at least take the crank sensor out and clean the crap off of it if there is any. Also if this is a 350 which it maybe or 5.7L take the cap off and see if you can move the rotor one way or another if it moves your dist gear may be worn out and your timing is getting screwed up. We are not magicians and go only by what you have described. Especially hard with you not giving any data on truck other than year and model.
