Intermittent problem with 2019 GT3RS
Driving home from a track day where the car ran flawlessly I pulled up to a light and all of a sudden my car started misfiring and the check engine light started flashing. This went on for about 10 seconds and then cleared up. I got a warning on the dash to consult workshop but no solid check engine light. Drove home without any further issue. Brought the car to an independent shop in the morning and there were codes for cylinder 2 and 3 misfire. They decided to replace all spark plugs and coil packs. They test drive the car and all checked out. I drove home with no issues and the car ran great. I went to back in my driveway and when I put it in reverse it started running rough again for 10 seconds and then cleared up. I checked codes and there were 2 pending codes for map sensor and airleak but no misfire. I drove for another 30 miles with no signs of an issue then the check engine light went on again. When I got home and went to back in the driveway the car started running rough again and check engine light was flashing. Shut it off and started up again and all was normal. Checked codes and it has codes for cylinder 2 and 3 misfire, random misfire, airleak and map sensor. Where do I go from here? Anyone had a similar issue?

2021 Macan GTS
No track for me in my Macan but sounds exactly like my Macan, now one month sitting at the dealer with no clue what’s wrong with the car. Porsche NA has now authorized a full breakdown of the motor

In my case that was it .New RS take the air from side vents ,you'll be surprise of how much dirt is in the air box .I'm on my sixth Porsche and never seen anything like that.
