How are you doing Sir or Ma'am, I currently been having a problem with my mustang hesitating when I take off in all the gears I go through. I noticed it only happens when the car is cold or not warmed up yet. If I let it warm up it does not do it, if I fire it up and take off within 5 min it will almost stall on me when I am giving it gas, in all the gears. It just starting happening, and I take care of her on a regular basis. Tune up, oil changes everything.
