Default Re: 2007 engine does not run like 2006 engine.

Hi Humtech,

Thanks for the speedy answer!

Should I ask the dealer to flash the latest update to the 2007 computer, just in case something has gone sideways with the present calibration?

The 2007 has a definite growl (louder, rougher and deeper sounding idle) than our 2006 had at idle. The difference between the '06 and '07 seem to disappear above 1000-1200 rpm.

Are the H2 engines hand built, or for some other reason is there a difference from engine to engine that could account for the different sound tone of the engine? The engine vibration changing with RPM is also different (more pronounced on the 07).

And yes, I hear you about the dealer covering their butt on the over-tightened oil filter. But I figure a newbie did the oil change. I only tighten hand tight. The guy overfilled it too, and this is pretty hard to do on an H2 due to the hole markers in the dipstick end, which clearly show you how full it is.
