The fuel rail was mynext guess. I'm going to repair the exhaust tonight then check the map sensor then move to the fuel rail.

Similar problem with my Jeep when I first bought it used. Idled fine, ran ok if I proceeded very slowly and would make it up to 35-40, but then would go no harder. If I tried to push it harder it would bog and backfire. Had me stumped for a week. Had new fuel pump, filter, plugs wires, coil, cap, rotor, ands sensors tested ok. Finally I pulled the fuel regulator to test it's flow with pressure from my air compressor. Seemed to be just fine. As I was reinstalling it, I paused, looked again and realized it should have two small o-rings. One was missing. Probably broke and then fell off some where when I pulled it out. The bad/missing o-ring was allowing fuel pressure to bleed back to the tank away from the injector rails. Have you had the fuel pressure checked yet, one more possibility there.
