2003 GMC Yukon XL 1500 Me engine starts and runs fine, there are no faults on my reader. When the car is placed in drive, the engine will sputter and fail. Any ideas?

What is your question?
I checked the air intake connections, no failed rubber noted, when the car is in park, the engine will run great.
How long has your 2003 GMC Yukon XL 1500 had this problem?
Sounds like excessive air getting into the engine or not enough fuel.
If there's an air leak, a technician will introduce hydrocarbons to see if the idle smooths out.
Has a fuel pressure test been performed at the fuel rail?
