so i recently bought a skunk 2 throttle bofy and manifold for my 2000 civic ex coupe and the throttle body is 68mm wayyy to big, it was trowing codes and making my car run like crap considering i needed to get an iacv module since my stock manifold didnt have one? now that i do my car is still running like crap and almost 2 steps at 1700rpm to 2200 rpm. my car is throwing codes about iacv and speed sensor and i dont know what to do. please help.
