What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Currently struggling to loosen at the manifolds. Had the breaker on the one nut that is reachable without wobble adapter. Nope!
Don't want to break.. Gonna soak them. Didn't because I lost the straw on my liquid wrench.. I'll use a brush.. I'll get there eventually..
Got cleaned up so I'm taking a break now!

Thanks for all the help! Be a day or two before next update..

BTW, has anybody ever check engine load at idle on their Tech2?

Load in what regard? I’ve not done it with a tech2, but my scangauge usually shows around 16hp at idle.

I maybe just lowering the pipe to test as j91z recommended!

I was going to gut them temporarily if clogged, but I have smog this year and dont feel like doing it twice..

The dang CARB ypipe is $2000! (or $1600 from rockauto for a ripply aftermarket one) Apparently CARB testing costs $1250 per unit! (non carb tested, carb compliant setup is ~$350)

Might be time to buy a beater backup car..

One of the great things about moving to a Free State is never having to deal with smog and CARB BS.
My Yukon had its last smog check when I bought it last year.

ouch. are you up north where stuff is rushy?

if not I was going to say hit it with an impact. the shock tends to help, but if you're in the rust belt. I don't deal with that stuff and it seems to he a whole different world
