1993 ford ranger 2.3
this has been boggling me for a few months now.
My ranger has been missing really bad for the past few month, all the time,not just when i first start it but constanly.It started when my catalytic converter stopped up ,so i cored it out, it melted 2 of my spark plugs , so i changed all eight of them,then i changed the egr valve sensor,idle air control sensor,o2 sensor.Well then started burning oil really bad so i replaced the valve steam seals.It idles with a horrible miss,and runs with a sputter. Im only getting 142 miles on a full tank of gas, and only thing left i think i could replace is the ecm. ANY IDEALS
