My 2001 ford explorer sport, when I press the gas it hesitates and want pick up speed, it use to pick up slowly but now soon as the car gets warm it starts hesitating and when u hit da breaks to pull over it kills, and to start it u have to turn it over like three or four times before it will even start, I have done a complete tune-up, changed egr val, and put in a new fuel pump and fuel filter still with the same problem. Can yall please help me, dont knw what else to do.
