Hey everyone, I have a 2000 mustang v6 automatic. When I attempt to accelerate from a stop, or even just slowing down for the person in front of me to turn, my car hesitates or lags. I can have the pedal all the way to the floor and not go above 10 mph. (from the complete stop) and you can see the rpm gauge kinda vibrate from the "trying to go but cant quite make it". It is hard to explain over the internet lol. Problems in mind are: fuel pump, fuel regulator, a sensor, or exhaust. Has anybody had this problem?
