Ok I got my truck back together and it starts great and it idles smooth and excelerates fine at low speeds but once you hit the highway and a hill it flatlines and you can gradually get up to the current speed. I changed the computer out a few years back and now that I think about it, My truck is an 92 bronco with a 5.8 and I pulled it off of an F150 5.8 but I don't think it was 4 wheel drive and I don't think it had an E4OD transmission in it. Could this have anything to due with the acceleration even though it looked like my old one which was bad.This is my last hurdle and I'll be happy. So if any one has any thoughts about this computer swap, let me know.
