Im having trouble accelerating , to pass slower traffic.
My problem occurs when I apply the gas pedal downward to pass a slow moving vehicle, and suddenly The engine starts to have Hesitation to accelerating, almost wants to missfire and shut down, but when I release upward with the pedal it seems to catch up and run a little smoother, . But reappling the accelerator again , engine starts to missfire and perform strongly to shut down ,and possibly stall. I replaced the fuel pump a while back , but when that went out , the ranger didnt start at all. Can anyone help? Im frustratrated. .
