2000 Kia Sephia Question: Motor will not rev... just boggs down

 

Question

Visitor, 1.8L 4 Cylinder, Owingsville, KY, March 14, 2011, 23:32

Had this problem before changing motor. Opted to change motor due to other problems with rings & cylinder damage. Changed motor and all sensors on the motor and intake manifold. Did not change MAF, IAT, O2... Fuel pressure on fuel rail stays in specs at idle or throttled. Wondering if I just happened to get a hold of another bad TPS sensor to go with the one I might already have. Any ideas?
