    live data dump. what do YOU see?

    Do us a favor and post properly-oriented pics. Ditto on Mass Air Flow reading in g/sec - much more accurate than the imperial scale. What was the issue before the parts were replaced? And now, besides the obvious mis-fire on cyl 8, what's the specific complaint?

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

    When you're tagged, you may want to take time to read what people point you to. @donjetman posted the link to the TSB in response to your question in another thread: https://www.tahoeyukonforum.com/threads/oil-out-the-exhaust-codes.158919/post-2057414

    02 Yukon motor tilting down at firewall

    Moved you here from the 2021+ section. Why not tag @Moosemoon (like I did here) and ask if there was a resolution?

    The OP hasn't been on here since the day after posting that (March 27th), unfortunately. As to your question, look for "solid" lug nuts, not "capped" ones.

    Intermittent Starting problems

    Start with a fuel pressure test. Gauges can be "rented" from many auto parts stores with a temporary deposit. See link below but navigate to your specific vehicle. You may need to monitor the pressure as you drive, but it sounds like it happens when attempting to start...

On the other hand, if the PURGE solenoid (on the engine) is malfunctioning, that can cause the engine to run rough (rich) by allowing fuel vapors into the intake when...
