acceleration pulsing on w22

[lsukev]

i have a 2005 hr admiral on a w22 chassis.lately i've noticed it seems as though it pulses forward or hesitant when accelerating, especially at low speeds, from dead stop to around 30 mph. i originaly thought it was a full water tank causing it but have emptied the fresh water and it's still happening. any ideas what could be wrong?

In the old days that would have been a carb issue however today they don't have carbs any more.. They use computer controlled electronic fuel injection systems.

A vacuum leak may be able to do it as well. I've had that happen to me on older rides. One lost a PVC valve and the result was just as you describe. (The valve was "Open")

Or .... A problem with the accelerator rheostat

I'd suggest you have a professional check it out. The computer may well know what's up if someone plugs in a diagnostic tool.

I have noticed my 07 w22 do same thing, from stop to about 30-40, real light on pedal-usually when cold though. I have not noticed it enough to concern me, I only fealt it 5-6 times and coulda been so light on pedal that was making it hesitate???
I know I was no help, just adding to discussion.
