I have a 2003 996 with 70k. In normal around town driving there is a distinct hitch in the light to steady acceleration. It almost feels like the AC compressor is turning on and off. I turned the system completely off and no difference.

In the old days (on other cars I have owned) when you let off of the throttle, there was an actuator that kept the throttle from snapping shut and creating a bucking effect. This actuator "caught" the throttle and eased it closed. Does the 996 have this?

I have tried:

TB cleaning
Motor mounts (which made the engine much smoother BTW)
New air cleaner

Thinking about new plugs. Maybe one is missing and causing the "compressor on" effect.

Other than that, runs great with lots of power.

I have read posts on engine surging but that is not really what is going on.
