Hi All,

The service engine light came four days ago. I use my scan tool to retrieve these code's. The car run's smooth with no smoke or any other symptom's.
I ran in to similar problems last cold season. Some of the same code's. I was getting rough idle and white smoke when we started the car. I posted last year & got excellent results from the feed back. It turned out to be the CCV (Crancase breather valve). I replaced it and all the faults cleared and the car has run fine ever since. I think it was in March of this year I replaced the CCV. Note: The one I installed was the cold weather one.
Thank you in advance for any help.

Jay
