I am having the same issue. Seems to start fine when cold but after engine is warm I have to tap the gas pedal for engine to start and keep running. Have you solved this? 2006 Buick LaCrosse
Fixed: Did a thorough cleaning up throttle body/plate. Take off 2 clamps going from air cleaner to throttle body. Use throttle body cleaner only and a toothbrush. You can manually move plate to get other side. Used about a half can. Afterwards started much better on my 2006 Buick LaCrosse 118K miles.
2013 buick lacrosse 73k. Stalls out in reverse. Immediately restarts on its own, even while in reverse. Code p0011 and p0010. Dono u Der stand why this isn't a recall yet. Anyone else experience and resolution.
