I have a horrid miss in my 2.3 ranger. here is what I have already done... Replaced; IAC valve, TPS, Cam sensor, Spark Plugs, Coil packs x2, wire set, fuel filter, oil and filter change, EVAP valve. Checked; charging system, Fuel injector operation, EGR valve and flow sensor, manifold vacuum system including lines and gaskets... no leaks, EVAP system check.Was driving down freeway when it started to buck, took over a month for it to throw a misfire code on cylinder #3. Checked compression on all 4 cylinders and all are within tolerances. what else could be the problem?
