So my check engine light came on with the code p0505. So after going through the possible causes for the cel(cleaned the throttle body,replaced the iacv, double checked vac lines.) It popped back on. While I checked the vac lines I was curious and unplugged the iacv, and it idled fine. So now I'm stuck as what to do next. Can someone help me please, any help would greatly appreciated
