Hi when I first start up and drive off the car travels as normal but then loses all power (motor only) when going up a hill. This does not happen all the time and we have replaced fuel filters etc. The car is an automatic. Once pulled over the car starts again and drives off as normal
Is the Check Engine Light showing when this occurs?
Did you check the accelerator cable to see if there is too much slack in it?
Ensure the floor mat is not too thick and afffecting the gas pedal travel.
