    Shifter Bushing 2012 Yukon XL Denali

    There was a dorman piece i got from o'reillys that has kept me safe for well over a year now. If you search on here, you will find some successes. I forgot the part # but definitely purchased locally from o'reillys and under $20.

    Check those motor mounts, a weak spot on these trucks.

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

    Cleaned throttle body and MAF at 247k miles. Last cleaned around 150k and didn't remove throttle last time. I did open the flap a bit to fit toothbrush for cleaning but no relearn process needed.

    Bad o2 sensors? Volt video

    Just an update, when I changed my upstream sensors, I seen the old ones were white. I did get a lot of bank lean codes lately. I believe they were OEM. The denso have more holes. I'll try to post some comparison pics.

    Replaced both upstream sensors and cleaned throttle body @ 247k miles. The driver side was crazy difficult to get to and I had to remove tire and plastic wheel protector area just to get to this sensor.

    Bad o2 sensors? Volt video

    Still have original sensors installed during video and have denso o2 sensors in a package waiting. I was told denso works well and they get a lot of good reviews. So far, same code still exists for bank 2 lean. I planned to clean throttle body and possibly install o2 sensors

    Bad o2 sensors? Volt video

    So I originally had 3 codes, P0171, P0174 and somethin for cats. As I drove more and I guess sensors woke up, most of the codes went away and my CEL light is now off. Not sure if I'll pass inspection. I only have P0171 for Bank 2 lean. I bought 2 upstream o2 sensors and waiting to see what...

    Bad o2 sensors? Volt video

    Can anyone confirm if these are bad o2 sensors? Coffee p0174 and p0171. Just replaced cats. 247k miles. I believe denso there way to go off they are bad. I'm at idle revving whenever you see the sensor 1s move a lot

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

    Thanks to this forum, I was able to research last time my throttle body was cleaned and it was back in like 2017, a good 100k miles ago. I know because I was struggling with the idle relearn process LOL. But I'll get some chevron injector cleaner and i think this time remove throttle body and...

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

    Just wanted to say this thread is a godsend to get reminders of when you did repairs on your car. I forgot when I changed my plugs but seen it was in June 2020 around 210k miles. Currently Jan 2023 with 247k miles. I see a slight idle issue and I know its not plugs.

    How to activate RSE without DVD

    I thought people could play video games in the rear if they hooked up a console so it has to be more than dvd that triggers it, no?

    How to activate RSE without DVD

    I have an aftermarket front unit that lets me control the rear independently. Since the original HU anticipated the rear for seperate dvd only, i wonder if its limited. There should be something that triggers the rear unit though.

    Just installed a Kenwood 1057XR 10.1 display head unit

    2 questions 1) Kids, how are the kids with this? Wasnt sure how flus it was against the trim but any issues with kids trying to pull on it? 2) Top vents? Do they blow air at the unit?

    New stock exhaust manifolds or headers?

    I'm getting high flow cats installed hopefully this weekend and bought exhaust manifold gaskets and ARP bolts. I'm basically doing a header job without doing headers. I know cars with headers need a tune but weighing my options here. If I dont get a tune, will i suffer? Looking for reasons...
