98.5 svt contour. I took the screen off the bottom of the fuel pump and ran the car. Now if I give it good throttle accelerating in first it hesitates badly making the car jerk very hard. Before removal, the car would have hesitating accelerating over 3000 rpm bad not as bad as now. Once I get into higher gears, the car runs smooth. What can be causing this new problem. Also, if the fuel pump is bad, what is a good aftermarket replacement? Thanks.......
