I have a 98 Ranger XLT. Purchased for 1500.00 Body in perfect shape. Was very rough driving home first time. Checked engine codes. Miss fire on 2 & 4. Changed plugs. No codes but when coming to stop engine dies. no power in 4th and rpm drops off. So far have replaced, the following parts= IAC, TPS, Both coils, fuel filter, Fuel pump, cleand out Cat converter. Will idle great at start up. when driven will die coming to stop, hard to restart. Anyone have suggestions what to do next.???? Help please would like to drive and enjoy this truck.
