Hey all, desperate guy here looking some answers. I swapped a d15z1 engine to my civic eg8 which had d15b2 engine. Weird? No. Normal engine in that car here in Finland. So i got it running and it runs absolutely perfect but i got CEL and code 48 and horrible MPG. I found out that one wire was open and i fixed it and CEL was gone. Now only code i have is 20 which i believe to be ELD. So i went out for a drive without CEL and it was awful. Everytime i tried to accelerate it felt like it has no fuel coming to cylinder. So i stopped and unplugged the o2 sensor, CEL came on and car was running perfectly. No hesitation at all. So what can cause this? I have checked the wiring few times, i have no codes (only that ELD). Is my o2 broken? I also have very low idle when engine is in operating temperature.
