I saw that you had an issue with passing emissions because of your ima problem. I am in the same boat. Did you just do the basic unplug your battery reset or did you do something else? Thanks, I really appreciate the help.

Did you get your P1457 code resolved? (posted here: http://www.insightcentral.net/forums/problems-troubleshooting/13464-check-engine-light-help-2.html) I've had the same for a few months. There was a TSB 03-001 (published in 2003) for a bunch of Honda models including the Insight. Says in salty conditions the EVAP Bypass Solenoid Valve could corrode and fail. Wondering if you replaced that.
