Well, this is odd. I'm reading a lot about this 410 code, but the service guy told me that was not a problem. Said it was Code 457 or 459; he couldn't remember (

). So, he cleared it, tested it and that was that. He said the EMI light can come on if the gas cap is loose or if the gas is over filled. Since Oregon doesn't allow self fueling, and service guy said cap was tight, I'm guessing the gas jockey topped it off and it was just too much.
