well after turning 151000 miles, the egr valve code decided to appear, need to swap it out, but the temp outside is 7 degrees and with the windchill, minus 15, so guess I will wait until the warmer weather comes around

 

My Dak ran really poorly when I got the code. I cleared it a couple of times, but it was OK for very short periods before it started running bad and would stall. All the symptoms cleared up once I changed - thankfully, the outside temp was good for wrenching.
