fine, when at slow speeds it drags? ? At one point i was driving in the city with lots of stops signs and lights and the car just shut off. i assume it got hot and senors shut it off but my car never overheated on the dash. after that it just got worse. When im driving fast on freeway car is fine drives smooth. When i get into a town with stops signs and dips etc it drags and doesnt want to go normal speed and i dont know why? ive had tons of work done already and i just dont know what it could be. And also my brakes lock up on me randomly i got brake pads and my brakes checked but i dont know why they lock up and start pulsating like something is loose or going to fall off but mechanic said they look fine.?? help please!??
