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

Received an updated tune from BBP. They said the P219A code was an issue with one of the Bank 1 (driver's side) fuel injectors. I'll pull them out and try to clean them. I asked about upgraded injectors, and if my current tune could support the next size up (currently have 32lb.), and they recommended Denso 50lb. which are less expensive than I had thought. I'd need a new tune for any new injector, and may just buy the full set in the near future.

Still am dealing with a cam CEL, but I might try swapping in a new sensor to see if that goes away.

Haven't touched the CAN issues yet.

That's exactly what I'm going to do. Need to run out to Harbor Freight and get some supplies.

You were in my neck of the woods.
I'm sure you have plenty of bugs all over the front end.

Soooo many! Better bugs than a deer though.

Which push bar / bull bar do you have on the front?

how was the animal population? I went last year in July wasn't hardly any bison or much of anything, when by comparison of going 10-12 years ago there were bison herds all over, elk, moose, bears, you name it only thing I didn't see was a wolf but they had only been re-introduced not long before then.

man I see so many posts of automatic trannys going bad left and right. I thought the 4l60 had a bad rep when used hard, all these newer 6 and 10 speeds seem to lunch themselves at $8-10k a pop every 150k miles less. at least the poor. 4l60 lasted forever if just daily driven.

what happened to drivetrain reliability the last few generations across all these automakers.
