Z bucks on acceleration
 

My z is a 2009. I bought it used 2years ago and it is bone stock. On occasion when I accelerate it will buck and the tractin control comes on for a second. Almost like it has stalled then picked it sef up. I wish I culd explain it better but it all happens so quick. And sporadically. Could it be the rear tires.? Deferential ?
I don't drive it now that it has gotten colder but I just ordered some bridgestone s-04 pp . And was planning on the differential upgrade kit. Maybe that will help.
Any ideas?

If traction control flickers its probably cutting power, that could cause some bucking

I've heard a few guys have the same problem but didn't get told how they fixed it. What dealership do you use? Hall Nissan in Virginia Beach normally doesn't charge to diagnose problems like what you're describing and tries to get it covered by the warranty where possible.

Could be wheel hop from blown differential bushing.

Turn off traction control.

Traction control smacking you in the face. :rofl2: Turn it off and see what happens.

This is what i was thinking. When i get a chance ill take it to browns nissan in sterling. If i can get it out the garage.

Look to see if you can see any brown/black stains on the diff cover.

Unfortunately I don't have a way to lift the rear end so just got on my stomach. Didn't really notice any streaks. But I was only looking from the rear. Next month it is due for inspection so they can get a better look. I also plan to start upgrading suspension soon. Other then diff.bushings what are other weak points. I don't plan on tracking so I only want parts that will help on street. Don't want to spend money on stuff that I don't need or would be overkill. I only drive car in spring summer and fall,with spirited driving on 66 and 495. I like to do a lot of weaving!😄
