Re: My turn "Misfire Head time?"
How many miles on your 06 H3 before it started "mis-behaving"?

Re: My turn "Misfire Head time?"
15000 and i thought I was safe on vin # It started rough idel months ago.
It's at the shop and i told the dude i was the former brand mgr. at another dealer and he told me they have done 3 heads. so it was probally more like 6. i am looking at trading up to a 07 adv package today.

Re: My turn "Misfire Head time?"
Maybe wait for a V8?
I want to get extended waranty from GM on the engine after the work is done in case the new head doesn't fix teh problem down the road.
I think they should really put in a whole new engine not just a new head.

Re: My turn "Misfire Head time?"
we will see, at least a 07 would have the longer powertrain warn.

Get ready to wait, my Colorado has been in for over 40 days now. Parts are hard to get here in LA I guess

Re: My turn "Misfire Head time?"
Crap, that sucks man. Mine just started to idle rougher (than normal) a couple days ago - I'm currently in denial, but it seems to be getting worse, no check engine light. Of course, I'm paranoid and hypersensitive about it. 30k miles now, if it goes, I hope it goes soon...

Cool and congrats. Let us know about the power difference/feel in your new 07 vs. the old 06.

Re: My turn "Misfire Head time?"
Congrats on your new truck !!
Just curious - what was the VIN on your H3 ?
I?m (also) believing to be on the safe side (my VIN is like 1000 above the "problematic", truck is April 06 build) - but what do I know
Thanks !

Re: My turn "Misfire Head time?"
The power diffrence is noticeable during launch from stop. It is nice to pop off a little better. i belice the cpu is doing things a little diffrent too. Going from base to ADV is alot more diffrent then i thought it would be.
My vin was several thousand past the number posted here in a previous post.
