I baught a motor from a salvage yard for $730 and the guy told me it is good motor, don't smoke or knock or anything. But we got it here swapt the intake plenum cause the motor is a 91 and my wiring harnis is 1990 as the car. But everything is hooked up, I did a tune up, (oil, plugs, wires, new coil) but it knocks and if u give it alot of gas it blows black smoke. I know black smoke is too much gas not burning, but the knocking. Please please help

Return the motor for a refund? Get the $$$$$$ back and get one that has no problem, you don't need this kind of stuffs-you wanna nice decent ride not half dead that will dump you out in the desert that will cause you to walk 300miles back to get help I've been here before and its not funny.
