Re: This Just In... All 2008's must run PREMIUM!
I've got about 4K on my 08 and she's running like a top. Yes, the idle is rougher than what it was in my 06. I've been burning regular in it since day 1. Maybe will try a load of hi test in it to see what happens.
I recall when they bumped the ponies up in the avalanche from one year to the next, the newer one had the same rough idle situation....went from an 03 to an 04.
