Jerking When Releasing Gas Pedal Suddenly

[arcenite]

Hey guys, so I was wondering what might be the cause of the jerking sensation I get when I release the gas suddenly. It doesn't happen if I do it smoothly though.

Anyone have any ideas?

Worn mounts and/or rear end bushes

cheers mate, any recommendations for a good engine mount that doesn't make the idling too harsh?

Nissan ones...

Yuh, echo that. Nissan, or for slightly firmer, the Nismo equivalents.

But as already meantioned above, it can be the engine, gearbox, diff, subframe mounts. Any and all of them. Could also be excessive lash in the drivetrain (diff gears, tailshaft centre bearing, CV joints).

It's often an exercise in trial and error to find and fix this stuff.

I'll probably bring it in for a check then =/, looks like there're too many potential issues that I won't be able to problem solve on my own. Thanks for the recommendation/help guys!

This is just part of life, a sucky part for sure. I have experienced this sensation all my life. It doesn't occur all that often but occasionally. I feel the burn shortly after Jerking. Forcing out small amounts of urine temporarily relieves the pain but after a while, standing anywhere and just forcing out a drop at a time, it becomes more frustrating than painfull. Through the years I have attempted various relief efforts. Ice, topical pain relievers, water, nothing works. Feels like soap in it. Always wondered if it was sweat or dirt that irritated it. Ive realized that it is more likely to happen after ive had small amounts of alchohol. After much trial and error, I HAVE FOUND A WAY to stop it. It may sound odd but it works for me. Its rather easy as well. Simply jerk a second time. Its like pumping your brakes. Cleans out debris and air pockets. Easiest way I can explain it.

I find that drinking a ton of water at one go helps a lot, the 30 secs of pee that follows helps to clean everything

It could also be an effect of the BOV set too hard, or not having one at all.

I had this. I put up it until my car got written off. When I took the engine out the rubber mount on one side was cracked. Im certain it was the mount on the engine because the gearbox had a brand new mount and the ones on the diff and subframe were pretty solid when o got them checked.

It's got the stock BOV though, so it's possibly the engine mount. Hopefully it'll end up being a simple fix and not more than that, I'll get the diff and subframe checked anyway just in case.
