Ok, so I tried the vac lines and nothing changed. Changed the Fuel filter thinking that was bad. this seemed to help at first, but now it is back to doing the same thing. No real acceleration. Boggs down at about 3gs and shifts hard or not at all. Once it gets past 1st and 2nd gear it runs fine, but still can't punch it and get the acceleration I use to get. Also there are times when I do try to punch it and right when i think it should shift, or it feels like it should, the engine sputters and I here a quick sputter hiss, like a line being blown out? Any idesa out there? any suggestions would be greatly appreciated.
