ok Ive been to ford and many mechanics.. finally had a "good" diagnostics done from a friend.. it was a misfire.. well the plugs, wires were changed.. nothing.. so I put a new coil pack and for the first 20 minutes it was great then went back to normal.. in low rpms it hesitates. as well as in higher rpms.. it hesitates likes its jerking?? could this be a fuel pump?? wouldnt that show up on a diagnositcs run??? please help guys I love my car but at times I just wnat to get rid of her.. thanks for any input.
