code help: p0450 & p0221 on engine replacement
 

hi guys, i have a 97 CA emissions CE and the block threw a bearing. so I bought a used engine from a trusted junk yard guy that i know well. the donor engine was a 99 CA emissions. He said the engine was in perfect condition before they took it off the car but when I installed everything, the car threw these codes and smokes a lot. Also, burns gas like crazy. Could the codes be causing the excessive smoke and very poor gas mileage. thanks in advance guys!!
