2006 LaCrosse 3800 engine have to give it gas pedal to start when warm? No error codes...

I notice that when my car is warmed up I have to push on gas pedal a few times while cranking in order to get it started. Then I have to give it fuel for a little bit before it settles in and idles smooth. Kind of like the old days with carb/choke problems.
I would think if it had fuel pressure problems it would throw a code...
Any ideas?

One of GM's best engines. Try cleaning the throttle body. Also a leaking injector can cause this. Fuel pressure low would show up under acceleration.

Thanks. Car just died and now I have no spark. I started another thread.
