1987 2.5 wont run right

I have a 87 2.5 that I have rebuilt. Put it all back together and now it wont run correct. It will idel fine with no problems but when you drive it it backfires and has no power, its sounds like a timing problem but I have checked it several times and does not seam to be the case.
Does anyone have any ideas on what should be my next move?

Double check the timing, plug wires sequence and all vacuum connections. Have you set the dist on #1 when on TDC?
