Hey guys I thought this was a well known own fact till my last customer stated they had been to the local GM dealer several times for a start and stall unless the tap the throttle and keep it running then it would run normal the rest of there trip . I chuckled and explained a simple throttle body cleaning would cure it for another 50k miles. so I spent 5 mins cleaning there throttle body and they were amazed and asked why the dealer didn't know of this and I said I had no idea I thought everyone knew! So if you don't know now you know
