Well , I just finshed verifing the tubes going to the dpfe sensor, boy is it inconvient. You have to take out the whole air intake system. Anyhow one of the tubes was almost disconnected, right on the edge. I took out both tubes and ran compressed air threw them, both were clean.
I started the car and check engine still on. I guess I'm going to have to drive it around before the check engine light turn off. Otherwise I'm going have to delete the code.
Would the dpfe sensor cause the engine to idle rough, Since it's related to the egr valve. I'm wondering if the egr can get stuck causing the rough idle??
