I got a 89 crx and I just installed a 94 civic d16 SOHC v-tech motor on it. I also bought a conversion harness wire to obd0 -obd1. now the engine light is always on. and when I check the engine code, I always have 4 and 9. So I bought a new distributor and it didn't solve any of my problem. I also tried taking off the wire conversion kit. engine Light goes off but car won't start at all. any sugestion would help here.....

by the way car runs good even with the engine light on.
