So I'm changing plugs a week ago and while I had the CAI off I decided to clean the BBK TB. Bad idea I guess. Now I have a high hanging idle that I can't find the culprit. CAI is sealed(checked twice), changed AIC valve, installed the Ford hanging idle fix plate. I had to close one port on the plate completely, and the other almost all the way. Just to get it to idle around 1100rpms. Without it while driving if I push in the clutch idle stays around 2000rpms. Until I come to a complete stop then it drops to around 1200rpms. What else should I be checking? No leaks and AIC is good. Didn't start until I changed spark plugs, should I not have cleaned the TB?
