Ok so my car’s rpms bounce at idle and i checked and cleaned the IACV then i read on here about the FIV and it’s like mine has the opposite problem of most i popped off the plate and tried to screw in the white plastic piece but it is loose like you can get it get tight or come out but when i put my finger over the hole for it in the TB it idles fine… so should i Just try and buy a new FITV or is there a way to repair this one? any help is apprciated thanks.
