Well, just because I hate reading about other people's problems and never seeing where they post what solved the problem they were having, I will post what solved mine.
The guy working on my truck had it for several months ( although he didn't work on it the entire time he had it, just when he had time to tinker on it )and tried several diagnostic test. Checked for vacuum leaks, firing issues, compression test and finally narrowed it down to fuel issue. we replace the spider injectors with a new set and my misfire on cylinder #5 is solved. Only parts thrown at it were 8 new spark plugs, distributor cap and rotor button and it really needed the plugs anyway. 182,000 mile and runs great.
