alright i have a 06 ls and when i start the car, if i put it in reverse first, back up, then put it in 1st, it will stall.(manual trans) or if i'm going down the road/high way and hit a little bump or something, it will studder, like it didnt get gas for a sec. anyone have any thought to what this would be? i just got it inspected today,with an oil change, also i changed the fuel filter. it still does it. thanks for the help.
