I just installed on of those import engines in my Millenia S. It was from an earlier year, but went in and hooked up without a prob. It idles great, but when I give it gas it won't hardly go. It doesn't miss, but I have codes. I used a carchip and it gave me these codes in order:
P0118,P0100,P0110,P0300,P1790,P0100,P0110,
P0300, and P0300.
It shows to have 9 problems. Do you have any suggestions?
Thank You

(based off what google indicates)
P0118 indicates a bad coolant temperature sensor/circuit
p0100 indicates a bad map sensor/circuit
p0110 indicates a bad intake air temperature circuit
p0300 indicates a random misfire (almost certainly a symptom of another problem)
p1790 appears to indicate a throttle position issue

Double check how your coolant temperature sensor, map sensor, and intake air sensor are connected. It's possible there are sensor differences between your old engine and the current one, comparing and swapping (if different) these sensors may resolve some issues.
