I have a b18b1 that have constant irratic idling during cold and warm engine operating temperature. I have replaced it with 3 different iacv, 2 map sensors, checked the vacuums, drained the coolant a couple times to make sure there is no air pocket or bubbles, replaced the throttle body and gasket. Am i missing something here that i forgot to do? I am in need of help badly, much thanks

 

theres no fast idle valve on the throttle body, fyi
