Don't they teach grammar and punctuation in CA? That's really difficult to read.

Is it jerking only when you accelerate hard? Is it surging, or is it mis-firing?

transmission mount could be worn off

did you do the proper break in of the clutch?

essejd

I have a similar issue with my 2007 and am at 91k miles on the 2nd oem clutch.

I don't think I properly broke in the clutch as this is my 1st manual vehicle and I got it just after the clutch change at 76k miles. Also on original slave/master cyls

you will have issues with the OEM master and slave... trust me... replaced mine twice

essejd

Should I look to replace the slave and master cyl with the heavy duty ones prior to needing another clutch change?

Is this an expensive job?

Thanks

yes and yes.. since you have the internal slave you have to drop the transmission out. if you ever change the clutch that is the best time to do it... if not acting up now leave well enough alone

when you get ready, look at the zspeed combo they sell

I just had my clutch changed and clutch master cylinder and I did break in the clutch the right way it's been doing it since I got the car 2 years ago the first time it did it when I first got it I didint think anything of it because it never did it again until just recent it will do it at least once or twice a week I even let me car run for about 5 mins in the morning before I take of to work. I got my car at carmax and got the warranty till 120k miles do you think I can take it there I know that not everything is covered and you have to pay 300 deductible and if they can't find the problem or the problem is not covered you don't get your money back so I don't know that would be a waste of money, I heard people say that it could be the throttle sensor **** how do you pin point what it is I guess I'm going to change my spark plugs soon and see if that could be ruled out

do the throttle position relearn procedure, and possibly reset the ecu also.

when you do the plugs, make sure you get the iridium, that is what the hr take... and get ready to spend about $20 each on them

calidrew909

How do I do the throttle relearning is there a link

calidrew909

I already did the whole unplug the battery and reset everything but the problem is still there the jerking

travlee

Is this when you are idling? I some times experience a back and forth jerking while idling with foot off the gas in first gear. I had assumed this was normal. When I keep a light foot on the throttle the jerking is usually gone. Does this sound similar to your problem OP?

essejd

Can't speak for OP, but the jerking is at lower speeds in 1st and 2nd gear. Sometimes it feels like a surge of throttle and if I let go while its still in lower RPM there is a sudden surge of deceleration. I just thought it was normal.

calidrew909

This right here is what I'm experiencing 1 st 2nd gear rarely tho but still I don't want that to be happening. I looked on the Nissan 350z recall list and couldn't find anything on there about this problem so who knows what it could be

calidrew909

In wondering if that surge could be spark plugs or something electrical

calidrew909

Mine usually happens when I come to a complete stop and go on first gear it jerks and that's with slight acceleration lol usually what I been doing as soon as it starts jerking I floor it and the. It goes away

Bro, I had my clutch slave cylinder replaced by the dealership several years ago due to the recall and I had the same issue. It was always at 1200 rpms no matter what gear but the worse in first going from 0 mph. It would go to that rpm then have a big surge almost as if the throttle was hit. It only did it after the install by Nissan. All I can say is: is something to do with an improper install by those half *** mechanics at the dealership. I've recently had my slave cylinder master cylinder and clutch replaced and the problem is gone. Hope this helps.

Edit: in short the problem is something to do with your slave cylinder or the clutch. It needs to be reinstalled or adjusted.
