    2015 Tahoe LT w/ “Hubcaps” ?!?

    I swear, I learn something new everyday. Looking at this Tahoe, you would think that the wheels are fairly nice. They look good. When I bought it, I didn’t even think that I needed to make sure they weren’t HUBCAPS! I reached down yesterday to wipe something off of one of the rims and it...

    2015 Tahoe LT 4WD Sluggish Acceleration

    So this weekend, I said f#%k it and floored it getting on the highway. No hesitation at all. There was a definitely lag in the response as it downshifted multiple times, but when it found the gear, it launched! I think it heard me talking about trading it in…

    2015 Tahoe LT 4WD Sluggish Acceleration

    The filter was pre-oiled. I didn’t add any additional oil to it. I loosened the filter cover and carefully moved it out of the east without disassembling the breather hose, and installed turn filter.

    2015 Tahoe LT 4WD Sluggish Acceleration

    This sounds like what it is doing. It didn’t happen all the time, but it happens frequently enough that it caught my attention. It seems like starting from a stop or slow speed that it may be starting in 2nd vs starting in 1st. Meaning, there is a lack of acceleration, like it’s a manual...

    2015 Tahoe LT 4WD Sluggish Acceleration

    I didn’t know that was a possibility. I will look into it. How does that affect fuel economy? I’m currently averaging 16 mpg. I drive 90% highway at 85 mph.

    Ok. That’s concerning. There is a definite difference between mine.

    2015 Tahoe LT 4WD Sluggish Acceleration

    My ‘99 didn’t have the active fuel management dropping from 8 cylinders to 4, so I don’t know if that is the difference it not. It almost seems like it is stuck in 4 cylinder mode when I’m demanding all 8. Not sure how I can test that theory. My 300c has a HEMI with active fuel management...

    2015 Tahoe LT 4WD Sluggish Acceleration

    I had a 1999 Tahoe 2WD and I don’t remember ever worrying about merging into traffic with it. I pressed the gas, and it would get up and go. It would put you back in the seat. I have a 2015 Tahoe LT 4WD with the 5.3 now. It seems to have no acceleration at all. If I floor it, it will not put...
