Persistent P0420 and P0430
Yes it is flexfuel, w/154,xxxmi - 123,*** by me. Always hesitant to say 100%, but I'm fairly confident they abandoned the physical fuel alcohol sensor beginning w/the 2006.5 models. GM went to the V-FFS multi sensor algorithm. I have, I guess you would say, "settled on" the exact thing you...- 5StarCustmSolutns

Persistent P0420 and P0430
Mine run same range as OP's? I do have a broken bolt head on #8 manifold. No visible sign of leak on head. Could this be contributing to a rich run condition? I've propane tested the intake area three times and found nothing, smoke tested the inward side twice and found an either. Just...- 5StarCustmSolutns

2008 Denali XL..Suspensions. From autoride to passive shocks and struts.
Confirmed this with Arnott days ago.. I was told Arnott does not make an OE replacement for the front of Z55 rides. Unless I read incorrectly(was in a hurry at time), Suncore makes an active OE replacement for the front end of Z55's; believe they were in the $350 range?- 5StarCustmSolutns

How much front lift to level z55?
I've probably spent way too many hours on this subject....but the general consensus I've received has been: Anything taller than 2 inches "under the shock" causes the front axle angles to exceed design specs of CV's and significantly increases the amount of friction heat wear etc. I was on a...- 5StarCustmSolutns

Howdy from the hills of WV
Hello, Thought it was time I said hi and thank you to all the members of this site! Seven years ago next week I purchased a 2011 Chevy Avalanche LTZ with 31k miles on it at a western PA Mitsubishi dealership. Almost immediately I joined the Avalanche fanclub site, but it didn't take me...- 5StarCustmSolutns
