Can anyone tell me what these codes mean?
My truck misfires on the fourth cylinder around 1,200-1,500 RPM. Checked compression was like 125 checked all fire its good and swapped 2 plugs and wires and still stayed on the 4th cylinder. I read somewhere that someone was having the same problem and it was the EGR Valve. Is that what this shounds like? Any help is appreciated. Thanks!
Hello all I just wanted to let you know I got my problem fixed today. I unplugged the vaccum line off the EGR valve and capped it off an bam problem solved. I may leave it that way to most say I dont even need the EGR valve. Anyone who wants to chime in on this is more than welcome. Thanks!
