We have had a cold snap lately (just coming out of it today), I have also noticed some mayo on the dipstick and oil fill cap. I know these are related to the cold weather problem with the EGR valve/system. Temps (when I start in the morning) have been in the teens F. I know thats not cold for some of you but my X, I am sure, doesn't have any cold weather options. I have read this situation can cause an idle misfire? Need I look into this more or am I way off the track? Hopefully it will start well tomorrow morning with the warmer weather. TIA.
