Changed the standard throttle body on my b18c for a skunk2 one larger diameter of 70mm from a 62mm , now it's sitting on high idle at around 2000rpm to 2500rpm and ideas ? Change back to a standard throttle body ? Or get it remap the ecu ??

disconnect your IACV (idle should drop to about 450rpm) and check for vac leaks.

might need to reset your ecu as it will be seeing different A/F ratio now with the larger TB?
