well it seems like I jumped the gun again, the check engine light went off again, this time it stayed on over night and through the weekend. I went out to start the car this morning and the light cleared itself....... so no chance the dealer can pull a code now. All I was told is if I can get it to go again, to bring it in and they can scan it. The upside is the new dealership totally understands what I am seeing and are just as baffled as I am whe it comes and goes. I will make a mention of the converter though Joani... thank you for that, it just may be the issue? I'm taking today off to get the code to throw and hopefully I can get to the dealership on time.
