[MetroMPG]

I'm embarassed to say I never even pulled the plugs on my Insight. It ran fine after the EGR cleaning and got well over 100 MPG US (aeromodded) in my typical use, so I figured they were OK.

I do remember sometimes the lean burn transition (coming out of it) could give a bit of a bit jerk though. (I also remember the pedal responsiveness got decidedly "mushy" when you go into L.B.)

Thinking about that car - it's amazing to me that Honda let the engineers get away with all the things they did in pursuit of uber-efficiency considering the potential impact on "consumer acceptability".

Makes you wonder what features / details / design elements were shot down by the decision-makers and didn't make it into production!
