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

[George B]

My Denali has finally relearned its idle position. For the first 3 days after cleaning the TB it was idling at 1000 rpm and you really had to hold it on the brakes at a stoplight. Plus the mpg was down to 11....

Filled up today and reset mpg meter now getting 14 around town...

This is the reason I haven't cleaned mine yet.

There’s a procedure for idle relearn but it needs to be done immediately upon start up or you have to wait for truck to learn. Had no problem cleaning and using it in my 13.

I had major problems, had to take it in to get forced relearn at the shop.

I don't get it I have cleaned mine in numerous vehicles numerous times never had a single problem, I clean them about every 3 months like clockwork. throttle body cleaner and a clean rag

I don't get it either. I've cleaned mine twice in the 2 years I've had it and never had an idle problem afterwards. I don't remove it from the vehicle or unplug it, just spray it while holding it open and use a rag.

Me too, never a problem.

I would expect none the less from you.
