Jeep Wrangler Engine Problem

I have a 1997 wrangler 2.5L. The engine went so I replaced it with a 1995 wrangler 2.5L. It starts fine, idles at about 800RPM's.
It lacks power and backfires thru the exhaust. I used everything from my 1997 as far as fuel rail, injectors, sensors, computer... Just swaped engines. seems like a problem with the fuel mixture or too much fuel. Please help!!!

Thank You.
