I was in a bad car accident in my 90 civic with a z6 in it. I now have a 88 crx and I have installed the z6 into it with a p28 ecu and I hardwired obd1 in it. I had some codes and fixed them and have no more codes anymore. My car is running rich and doubling the hc and co limit at aircare. I have checked everything and I am losing my mind and money fast.I am not working and I am still recovering from car accident.Car had a brand new cat and a working o2. has header and full exhaust.Is there something I could check that I may have overlooked? any help would be greatly appreciated as I can not transfer my insurance over till it has passed and the permits are killing me.
