Rough idle after cold start or at operating temp? My GT3 idle fine at operating temp.

 

Cold start the idle is jumbly and the transmission is sluggish. 2 minutes later its just perfection.

 

Same here, I have PDK and needs more acceleration to start moving when cold.

 

If you haven’t drove it much in NA since ED, the fuel trims could still be learning the different air since ED.

Cat warm up is also online for the first min or so of a cold start.

Perhaps the dealer can reset the ecu adaptation? It should sharpen over time as it learns however.

 

All this sounds familiar, it must be normal. I have a manual and it’s super sluggish until it’s totally warm. Thanks for the help, I feel better now.
