I swapped out my old f23a ulev motor to a f23a jdm motor. Now the car is slow Andy check engine light won't turn off. The code it's running is p1167 for 02 sensor. My mechanic used the same sensor that goes to my ulev. He also used the stock exhaust manifold. I'm just tryingto get it to perform like it used to before the swap and also make the check engine light turned off......please help.
