C32/C55 AMG
I'm having similar issues and I was thinking that it may be the intercooler pump, but I remember reading some where that the issue was related to a slipping gear or clutch. I feel the loss of acceleration in certain gears and other times the car feels like the supercharger is not engaging all the way. I need to try the the throttle reset.

Its all about throttle acuator?!?! I guest so.
Tested for serval months, here is the stat. hows the jerk came up:
-start still, jerk on light throttle, no problem in deep throttle
-hold the throttle on hwy then kick down deep, no problem.
-hold the throttle on hwy then push more throttle, jerk.
-The most significant when off throttle in D, it seems get into N some time. Check with shifting to N, no rpm drop.
What I mean is, the ECU can sense the throttle angel, but not engough power to keep the engine rev up, so jerk.

Please keep us updated on your situation cause I am having the same problem. I am thinking of replacing the MAP sensor (I got CEL for it) and replace the ignition wires. I also got a code for Cylinder 2 misfire, but after I reset all the codes, no CEL's showed up. The car is misfiring all the time and it jerks on partial throttle and is extremely sluggish and even though the tranny kicks down, the engine doesnt seem to have the power to match it. Let me know what you did when you fix it. Thanks in advance.
