What did you do to your NBS GMT800 Tahoe/Yukon Today?

[nonickatall]

Make sure you remove the oil dip stick, it will make your life easier to remove the starter

Here is a good tutorial..

But remove your battery first. You would not be the first who burnt down his car, while trying to remove the starter...

Does anyone have a subscription to Alldatadiy? I need the wiring diagram for the starter circuits

From my 04 factory FSM, if this helps...

I ordered a new accumulator/drier, orings, orifice tube, and compressor. My A/C compressor still works, but is a bit louder than it used to be and I've noticed the cooling doesn't seem to be as good as it used to be during the height of summer. Hoping some fresh parts and a recharge will get the HVAC back to operating good as new again.

So recently had my tahoe tuned and had them do an e85 delete. I unplugged the sensor, now I am getting a code p0178.. hate seeing that CEL

I’m just getting into tuning, but why? Is e85 not readily available?

My truck runs like a turpentine cat on e85 and would only get better if those tables were also tuned, but maybe that's not possible?

I don't use e85, and when I replace my fuel lines I plan to remove the sensor.
So I believe in my tune he turned off the sensor but didn't delete the codes that report a fault with the sensor

Same.. I LOVE corn gas!! Unfortunately it’s not available within 90 miles of me, but I may just pickup a few gallons here and there in barrels..

Turpentine cat - that's a new one. I usually say like a r- aped ape.

Heh...I learned that one from my father in law after we changed the plugs on one of his vehicles a number of years ago. I had never heard it before.

Was it @iamdub who wanted one of those sensors?
