Alright, i recently pulled my b16a out of my 96 coupe, and i dropped in a ls-v (b16a head) we swapped it in and it threw 3 codes and i fixed them right away(baro, knock, primary o2 sensor heater) fixed all of those problems, and it ran good for 3 days or so, pulled hard and had no horrible fuel comsumption. But the last 2 days it has begun to run very rich and whenever you get on it it drownds everything out and barely goes until vtec and that doesnt even pull hard when it crosses over. I have a skunk 2 intake manifold with a 70mm skunk 2 throttle body, and i pulled the fuel rail off of my b16 and put it on the ls-v( went from a round fuel rail to a square one because of the better looks, and fittings.

do i need to get either chrome, a vafc, or what should i do about it? the b16a was in for a few years w/o any problems other than sputtering here and there. I use gas horribly right now and its my daily driver.

thanks
