i have two months until honda day at atco race track in jersey and i have to get this fixed............i did a full motor swap b18 in my ek.......my idle goes up and down, up and down, even when the car is warmed up...i checked map sensor, tps sensor and iacv.....NOTHING!!!! still does it.....i have the right cpu in it..so i dont know...im getting it ready for boost but need to fix this asap..thx

 

I had similar problem, but mine was just throttle body was flipped over. I also replaced the idle air control valve. Might try those and see if it works.

 

Sounds like an air/fuel problem... definitely want to get that fixed before you turbo it out. Those b18 with turbos are real beasts on the street.
