So Ive searched around on here and Im just trying to gain some assurance before I drop more $ trying to solve my excessive EGR flow CEL.
Ive read pretty much every pertaining post about this CEL and Im pretty sure my dpfe has kicked the bucket.
Ive tested my valve with the vac test and it seems to be working propely. What makes me think that the problem is DPFE is the fact that the CEL seems to turn on while the car is idling.(seems like a sign from what Ive read on here). I used to have some idle issues but that was caused by a lean side (CEL). Yet that was cured with a easy MAF cleaning. Then I was back to only a excessive EGR flow.
Also the CEL tends to turn off at times and turn right back on. Now if it was the valve/egr itself, then it would always be on since it's a mechanical piece. Where as a sensor can seemingly have it's good days and bad days like a sick patient.
The car has 85K+ on it so it seems like it should be done anyways. Just trying to assure myself this possibly is the right thing being that I hear it's a pain to reach.
Thanks
