Hey all, today when I started my car I began having insane idle fluctuations. It’d dip to 600 then surge to 900 and go back and forth. My afr and vacuum gauge also moved with the fluctuations. I am curious if anyone has had this issue. I’m thinking it’s the evap purge valve. I have no cel, then if it is the evap purge valve, where is it’s location on the 2018 GTs? I know the 15-17 has it above the throttle body. Thanks.
