mine too.

when i had my d series i turboed it and i had the idle problem with larger injectors but when i adjusted the fuel with the vafc it smoothed out?????

now i have a b18 ls swap 94 in my si hatch and it idles too low then sometimes not always idles up and down! i was told that the throttle position sensor goes bad on them and will cause this but have not spent the 80 bux on trying this. i was also told that any tps would work but havent found any proof of this either so someone must know!

i have heard of alot of people having this issue but noone knows how they fixed it or wont tell!
