Will not accelerate unless I leave off the gas a little. Also, noticed when I pulled in last night that the headlights would flicker as well.

Good morning.
The first thing I would do is check the fuel pressure. Make sure it is within specs.
Check the throttle body plate for any carbon build up as well. that will cause hesitation.
Have you ever had the injectors cleaned?
