I have an '01 Ranger w/4.0 v6 that developed an engine misfire. I have done the following: plugs, 3 sets of plug wires, intake gaskets, fuel filter, cleaned MAF, cleaned idle air control valve, checked air filter, cleaned EGR (but still get codes PO401 and PO402 - excessive and too little gas flow in EGR), new coil pack. Miss starts after engine warms up and it is on a pull. Has anyone seen similar problems? Can anyone help?
