I bought a 1987 XJ that had 202k on it originally. New rear end, new front end, and 5-speed tranny. There is a newer (52k on it) motor from a tj in it. The problem is that when getting into higher rpms on each gear but especially fifth it backfires A LOT. I put new injectors in it as soon as I got it as well as new plugs, wires and distributor cap and rotor. With the backfiring it runs great at an idle but as soon as I get on it the motor runs real rough. Any ideas?
