Gilly,

Sorry about the delayed response. I thought that I was subscribed to this thread but I wasn't.

No. The check engine light did not come on. As a note, I did find out that the vent hose issue had already been addressed according to TSB 2008020002. I'm anxious to hear what any of ya'll might have to say about this strange problem. I heard that there were problems with the valves on this motor that is remedies by changing the whole cylinder head. Any idea what the "signs and symptoms" are of this?
