Engine Performance problem
1998 Mazda 626 4 cyl Front Wheel Drive Manual
My car start jacking while on motion as if the fuel system fails. It does not accelerate well, I thought my fuel filter is blocked & I replaced it. The problem continues until the car finally stop, I have change the fuel pump, Ignition coil & the problem continues. Later, I change the air flow sensor or AIS. But it runs but not effectively. Please I need to know what next?
