Engine Stumble Poll
#107
Done! However my car has the stumble in 2nd, 3rd, and the fishing line tug in 6th gear and the survey only allowed me to select one gear.
BTW, I suggest everyone start complying with their states lemon law requirements because the word from PCNA continues to be that the behavior is normal and there's obviously no fix at this time and none on the horizon.

I've confirmed that it actually stumbles it in all gears @2500rpm, but is so much more evident in 2nd, 3rd and 7th. Perhaps it has something to do with the ratios and power available.
I can modify the poll to allow multiple selections (or all) for stumbling gears.
PCNA would be complete idiots to open up the proverbial floodgates and have a wave of LL arbitration's come their way - at least 25 at last count.
Not to mention that we're already in class action territory - and that's when it's really going to hit the fan.
Stumblers of the world, unite!
Update - Because the poll is currently active I can't make any changes.
Hence I'll leave it as is for now. But TRUST ME it stumbles in all gears.

I don't know if it was wishful thinking or just hypersensitivity, but I didn't notice it stumbling in Sport mode. I was toggling back and forth between Sport and normal, normal stubbles, sport was not or was less frequent in sport mode.

I have even been in cruise control @2500 while being tugged to death, and attempted all modes. Nothing I tried made a difference - A/C, PSE, Sport+, hanging the wife out of the sunroof... Nothing.
The Placebo effect is alive and well.

No - you're not insane, because I too have "felt" this. However, after driving in Sport mode for a little bit, it quickly became evident that the issue persisted.

Little did I know that they meant something completely different whereby our crankshafts are apparently out of balance, resulting in a "harmonic imbalance" and the subsequent shudder. Needless to say, me thinks not.
As for the wife, truly my everything and more..

I have just completed the survey. I have felt this stumble or hesitation around 2500rpms few times before in 2nd and 7th gear but thought it was just the engine behavior at that time, fuel, fuel mix, etc...just a momentarily bad combustion.
After reading all these threads, I have made a point to verify it over a few days it and yes I can feel that stumble/hesitation clearly in all gears around 2500 rpms except 1st.
I must say that I also own a 2003 S2K and a 2013 E92 M3, which have high rev engines and though at low rpms and tall gears, the engines can feel less responsive; they behave linearly without hesitation.
Keep the updates coming...

I'm beginning to suspect approx 10% -20% of cars are affected, most of which seem to have developed the issue.
I know that my car developed this issue and it's not something that I suddenly noticed after the honeymoon was over.
Appreciate the feedback.

The sunroof episode was me exploring the "harmonic imbalance" theory that someone was blaming our stumble on.
Little did I know that they meant something completely different whereby our crankshafts are apparently out of balance, resulting in a "harmonic imbalance" and the subsequent shudder. Needless to say, me thinks not.
