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

[Just Fishing]

The heater hose adapter i bought didn't work, but I was able to remove the original.
Second time trying out my "ClampTite" tool.
Seems to work pretty well.

And i removed the remaining AFM bits from the tune and cleared the ABS code.
So far so good.

I think i need to replace that MAP sensor though.
Something weird about the way it idles down.
Almost like I have a vac leak.
Sprayed brake clean around, nothing changed...

Tomorrow i'll go grab a generic from the parts store after i take the hoe for a little drive.

What RPM does it idle down to?

 

[Just Fishing]

hp tuners shows 500-600
If i rev it, it just takes a while to get there.

If it’s not a vacuum leak, Might be the idle air control valve.

Check this out..

That feels right, i also saw something about the IAC in the errors for a moment right before i re-flashed it.
I assumed it was because i opened the catch can drain for a sec...

Guess it's time to learn how the fkn iac works in this thing.

Good luck!

However, i do actually enjoy this crap for some reason... lol

And i did fk around with the tb, put a new seal and cleaned the thing.

Seems related lol

Glad i have a tech2!
