I will try the injector cleaner - what do you recommend? I have read here that some like techron.
Techron is what BMW recommends and sells under their own P/N

Do you notice the tach move? If not I would say transmission, I just had the same problem with my 545 so BMW changed my transmission.

Yea Jeff - the tach would jump. it was definitely an ignition/fuel delivery system type issue. Misfire kind of feeling. I could even replicate it putting the shift knob to the "manual" setting and leaving it in a gear.

With the new plugs and two applications of techron, it is running better than ever for now!

FYI - after the techron and plug replacement, this problem has resurfaced.

I am taking it back to the dealer tomorrow. Hopefully they can replicate it or suggest something to try and correct it.

I will keep you all informed.
