what code is the check engine light giving when you take it to the dealership

you lose on avg 1 mpg with upgrading to the automatic, and i learned on a manual and my first 2 cars were, its a phase i grew out of.

after everything including employee pricing 500 dollar rebate processing and destination fee taxes and title and tags i paid 17370.66this is just with AC, Prefered Package and Automatic on a 1.8l vibe whose msrp (if built on the pontiac site) was about 18730

hey guys, just wanted to say thx for the site a lot of the info I found here went into my decision to purchase the vibe, picked up the 09 1.8L version, which btw was a pain in the *** to find around here.anyway ya normal new member stuff, great site, nice to meet ya etc etc etc
