Hustleman

I was wondering if anyone has had a similar issue.I have a 2012 A5 2.0T with APR stage 1 ECU remap. The car runs great with no issues except randomly when I start the car it will drop idle and die if I don’t give it gas. Once I give it a gas it idles high for a moment then finds itself and is fine. If I turn the car off and restart it works without issue. There is no error codes when this happens. Once in a while it gives a “system to rich at idle “ but that’s it. I have has the throttle body cleaned and it looks fine. Any insight would be greatly appreciated I decided to upgrade to an S5 and just replaced the pcv thinking that might be it because there is no code related to the issue but it still happens randomly
Issue happens when I put back in stock mode also but randomly. Once its started I can turn off and it will start fine
