yes...take it to a mechanic

 

sounds like you have a dx crx and whoever did your swap did the wiring wrong.

code 7 is tps, which either is wired wrong or the sensor needs to be adjusted

code 9 is cyp which is a sensor in the distributor. either the mpfi wiring conversion was screwed up or you got a bad distributor

code 14 is IACV. It may be unplugged or the valve is bad. They do go bad sometimes especially with old b16a1's

code 23 is knock sensor. Probably just not wired up or the sensor itself could also be bad.

Good Luck, if you need help fixing these problems pm me.
