    Steering wheel is offcenter after tire rotation and balance

    My 2020 Tahoe was absolute straight and steering wheel was dead on center. Dealer did tire rotation and balanced all 4 wheels. Well now the steering wheel is a bit off center to the left when truck goes straight. I know that this truck can ride straight with the steering wheel being dead on...

    Tune voided my Yukon warranty

    Speaking from my own experience, M-M Act or Lemon Law... These are laws but enforcing them is a) very time-consuming and b) expensive. Do not count on M-M or Lemon Law these days because GM claims their legal departments are short-staffed and are backed up by months and they take months just to...

    17 Suburban Premier - rough idle when warmed up

    @Tiredmechanic23 Agreed, I was thinking about changing ATF in my 2020 with 13,000 miles on it, what Mobile1 fluid is the good one? Many folks really favor Amsoil but GM insisits on Mobil1. I understood that there are several incarnations of Mobil1 ATF. It shifts well but I would like to get...

    17 Suburban Premier - rough idle when warmed up

    I used to have a thread here on rough idle which was over 50 pages long (or something close to that). My 2018 Yukon had rough idle when I bought it with 7K miles on odometer, spent endless hours and over $2800 of personal money to fix the rough idle and it was all wasted. Finally found a local...

    Catch Can

    On 2018 Yukon 5.3 UPR can was catching ±1-2 Oz every 1000 miles, no frosty milky stuff but oil with minimal gas in it. I think UPR really thinks hard about their design and keeping can really hot. 4-chamber UPR can was very effective. however, there are tests showing that RX cans catching a bit...

    2015 GMC Denali Lemon?

    Most states do not allow Lemon law on the vehicles that were previously titled even CPO, does not matter. Lemon attorneys would not even talk to used owners.

    GM Performance Drop-in Air Filter unboxing GM part# 84544587

    My subjective (purely by feel) experience with this GM Performance drop-in after 20 miles is the following: 1) Absolutely no tangible improvement in throttle, does not feel any different than stock. 2) Idle with this drop-in got "rougher", with stock air filter it was butter smooth, perhaps...

    GM Performance Drop-in Air Filter unboxing GM part# 84544587

    Actually there is very little difference between stock AC Delco and Wix. Wix filter a bit better at filtration but gets loaded and restrictive faster than stock. I would say stock AC Delco is a good balanced filter. However, point of this discussion why GM came up with this "Performance" filter...

    GM Performance Drop-in Air Filter unboxing GM part# 84544587

    Part # from GM site 84520923. Could not find answers to the questions about this Performance part from GM. So I am paying back to this forum with an unboxing of the filter to answer some of the questions. Is it a disposable filter? How often do you change it? Do you need to tune the truck to...

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    I did extensive comparisons of nine brand new and five low-miles Yukons/Tahoes ranging 2018-2020. Here is what I found. It is roughly 50/50 smooth idle vs. rough idle. I feel that it is a GM quality control issue, no other explanation. Not every truck has rough idle at ~500RPM in gear at engine...

    2020 Yukon XL

    Do take time to test drive and warm up the engine 10+ of highway miles minimum, then come to a stop with the truck still in Drive and let it sit for 20-30 seconds and then feel if there is a sensation that idle is "missing", skips or tremble. It is light but very noticeable. I test drove 3...

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    I have changed MAP sensor with OEM AC Delco 12644228, no change with rough idle. I drove 500 miles today and through some really hilly terrain. After up the mountain driving if I come to a stop rough idle even at raised RPM of 650 is equally as bad as at 500. I have checked and both electrical...

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    This is exactly what I have bit for bit... except mine is 2018 so many people have tried to fix it and all got the same "within spec" answer and learn to leave with it... that s a sad state of affairs with GM...

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    another interesting observation only 5.3 seem to have rough idle, 6.2 not much at least in 2019-20 lineup.

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    Thank you for the tip, indeed. I will make sure. I will try all that I can within reason to get the idle to be smooth. When I cleaned the MAF and MAP, idle was smooth for the entire 2 hours of driving yesterday, but today - back to rough... oh, well.

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    This is what Arbitrator decided. Rough idle is "within GM spec" as it not a safety risk. I am reading more and more often these days, that GM and dealers are using "within GM spec" execute for those items that are not safety risk but expensive to diagnose and fix. Interesting that "within GM...

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    Makes sense, I will double check for sure tomorrow. To match your setup, I have ordered Airaid Jr to try. It is interesting that there are no complaints of rough idle on 2019-20 vehicles, trucks and SUVs.

    Is there such thing as out of balance (engine, AC fan, etc.) that cause rough idle?

    Not sure how to tell but from the windows sticker I do not see the max tow mentioned. It has 7300 lbs. rating.
