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

Lol its probably a good sign the maf is bad if you unplug it while the engine is running and nothing changes

Side note. I did the test process that I linked on the last page. The MAF has good power going to it and a good ground. When I checked the signal it didn't change whatsoever. So based on that link the MAF is bad. Luckily I can process an exchange with Rockauto for a replacement. I'm thinking I got a bad one since I barely drove at all with it.

By biggest concern is. What if it wasn't a bad one. Is there anything I should be looking at that would cause a MAF to go bad so quickly?

Installing the trans in The Beast today. Got it bolted on, next is the transfer case. I hate installing the transfer case. Grrrr.

I hope everything works out better this time for you. I'd hate to hear about that trans breaking again!

Hmm put the new tires in the front. Money kinda tight so went to my used spot and got 1 tire and they are in the rear. Was gonna take the blown sub woofer out but do that tomorrow.

It's not called "The Beast" for nothing!

I just borrowed it from Advance Auto. I did blip the throttle and slowly applied the gas and there was no change.

I bought a new K&N filter to replace the old dirty and dented Specter filter and cleared the code. Its not raining anymore so I'm going to try another test on the maf if it comes out bad ill swap it out with a replacement.

Either the MAF is bad or there's an open circuit in the harness between it and the PCM. If you can find the pinouts for the plug(s) on the ECM, you can check for continuity. Do this before you replace the MAF. Or, if you know someone with a similar vehicle that will let you, swap the MAFs and see if you get a valid reading. You're currently running on a speed-density tune of sorts. I'm surprised you haven't noticed odd shifting in the trans.
