Drivetrain or possible Tranny ?
When I am going down a hill or coasting, if I am barely in the throttle, you can feel the car sort of jerk/lunge, or even somewhat surge. I noticed this before on my WS6, but in the Z06 I feel it more. It only happens when moderate throttle is applied.. Any help??? Normal??? :banghead:

Sounds like you need to make it to an event so we can check out your car for you :rofl:
Not sure what you mean.... It sounds like the normal "compression braking" where the engine's compression/rpm is slowing the car down.

At what speed and in what gear? My guess is that woosh is right but hard to say without the other info. If you are coasting in a low gear at high speed, then I can see how this would happen.

I'm crusin in 4th ger let out to coast to a stop, realize I don't need to come to a complete stop, give it a little gas and it jerks...It really does it in any gear. It does feel like the low gear high speed "feel" though...

Could the PCM shutting down fuel in a coast situation. The transition is never completely transparent (at least for me) and I feel the slight surge when the fuel is resupplied and the motor generates a little torque.

I'll try to simulate the coasting in 4th next time I have her out. May be that many of us just don't notice it or are used to it as being normal. On the other hand, it could also be that I never give her just a little gas ... it's always WOT :lolg:
