I have a 01 ranger 4.0 4x4 and I have a misfire at startup and then goes away after the engine warms up. At idle I have no CEL until I get on the highway with it then it starts flashing and goes solid after the skip stops.
The codes I am getting are cylinder 2 misfire and lean bank one.
I have changed the coil pack, plugs and wires, PCV valve and also the DPFE sensor.
I have also checked for vacuum leaks with no success.
Any ideas what could be wrong?
