EGR Carbon????
Ok I had an EGR finnally sunise to the carbon buildup so I bought a new
valve and replaced it. Prior to replacement I changed wires, plugs and pvc valve. Also prior to install of the new one I took a 12 gauge wire and swished the holes that it sucks through and then used a montster vacumm to suck out anything that I loosened up. That was a month ago and low and behold I get another SES ab nd code p1406 (which is EGR) If I reset the code then it will be fine for another month or 3 weeks then bam p1406 again. I took it off to inspect it and was suprised to find so much carbon in the holes again.. once again I did a thorough cleanning. My question is where does all of this carbon come from. I feel that I am just fixing the result and not getting to the source.. 1996 sc2 118k I might add that car runs great and smooth, isn't burning oil and gets over 40mpg hiway and 35 city. Thanks for any direction Phil |

Sounds like it may indeed be burning oil. Replacing the PCV may help.
