I have the same kinda problem. spent 5 weeks at the tuner everything has been swapped changed etc- injectors, coils, plugs, etc. Its a supercharged car but the car will stall when warm and deos not idle with the a/c on. Sitting in my garage as its impossible to drive currently. Not sure what route to go next.....

 

Logs need to be posted so some of us can see whats going on. Its the easiest way to find the problem via the internet
