I just had a fuel filter replaced on my car after having a problem with it not seeming to get gas. It will run perfectly then for no apparent reason I will have to floor it just to get it to move. After stoping and restarting it will run great again. Then for no reason happen again. It does not stall or conk out. It goes into drive & reverse very smoothly. Any reason for this to happen?
