2.5 years into ownership, and mine STILL does it. Latest flashes and everything up to date and working perfectly otherwise.

Resetting that eccentric shaft sensor thingie (turn key to on, tap brake pedal around 20 times very fast until oil gauge sweeps over and back) SEEMED to fix it once or twice (I have no idea why it would though). But not anymore.

I just live with it, and intentionally hesitate a bit now when releasing the clutch. It's annoying though, just KNOWING it's there... anticipating it to stumble.

I've turned off the TC/DSC (hold switch in until warning light pops on), and it still happens. BUT...

There's a certain railroad crossing I bump over on my way home from work. I generally stay on the throttle when I bound over the tracks, and I've found that it confuses the TC apparently... as it momentarily cuts the power for a second until the road smooths out again. And this feels *exactly* like the WOT bobble.

I'm not saying the TC is the cause of the WOT problem, but it's definately not the clutch... it's the engine cutting power for whatever annoying reason.

 

I have the exact same thing with mine... even with TC off...

 

I bought the car in Mar04. I drove the car for 9500 miles and did not have this problem.
After having the flash updated from K to L or M this problem appeared. When I took the car in for the flash I drove a specific route to the dealer a specific way (WOT, part throttle, ect) so I would have a reference to compare the new flash. 1/2 hour later after the new flash I went back the same way and discovered this problem. I firmly believe the new flash is the cause, it has to be something with the mapping or timing.

 

My guess then would be the timing. It could have been an early attempt to fix the heat and lack of oil issue. Now we are getting more oil to lubricate the apex seals. Anyone notice this with the latest flash? I haven't really noticed it.

Just an idea of course....

 

Through some "on-ramp testing" over the last week, this occurs from 2nd gear into 3rd gear as well. However, it is most noticable when shifting at 8k RPM. Going to 9k lessens the effect quite a bit.
