JEEP WRANGLER ENGINE PROBLEM

1997 Jeep Wrangler • 150,000 miles

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.

Start with a compression test to see what the condition of the motor.

How long did the donor motor sit?
