I have replaced my IAC, cleaned the TB 3x and still nothing. I did notice that upon spraying Carb cleaner at the line from the PCV elbow to the Intake Manifold there was a stutter.
Could you show me the bolts you are referring to? I am not sure if I need to replace the vacuum line or what. I am one weekend away from just taking this to the mechanic and washing my hands of this issue. Should I look into replacing the TPS as well? because a new IAC didn't do a darn thing but make it worse.
