no vacuum leak that we can visably detect (checked all hoses and they all appear to be functioning fine
replaced IAC
Replaced TPS
Replaced mass air flow sensor
replaced air filter
still on startup idles at 4000 rpms this really feels like a vacuum leak but still. We checked over and over again and there is no noise indictive of a vacuum leak and all the hoses are properly attached to the intake with no indication of a leak from the point of attachment
any thoughts or suggestions?
