Jerk issue - 2007 Nissan 350z (Manual Transmission)
Hi there,
I have a 2007 Nissan 350z that seem to have an issue with the clutch.
Whenever I merely press the gas enough to begin accelerating, the car jerks until it picks up a certain speed, then it stops jerking. It happens happens for like a second or two in 1st, 2nd & 3rd gears mainly, but less jerks on higher gears. On the other hand, if I accelerate quickly, it doesn’t jerk.
Even while cruising, if I lift my foot off the gas pedal & reapply it, it jerks again every time I do it, regardless of what gear I’m on at the time.
So I’m not really sure whether it’s a clutch, throttle or gear issue, or maybe something else I don’t know.
But about 2 months ago I had an issue where the clutch pedal dropped completely to the floor & it wasn’t releasing to come back up, to allow me to shift gears. So I took it to a garage & replaced the master & slave cylinders.
This somehow resolved both issues (the clutch pedal that’s not releasing & the jerk when accelerating or lifting my foot off the gas pedal & reapplying it).
However, a month or so ago, the jerk issue came back again.
So I took it to different garages, only to find out that their mechanics are completely clueless. Some were telling me that this is how the car is & this is natural, while others were telling me that I’m just imagining things. Honestly, it couldn’t get any more frustrating than that.
That jerk is so bad, that if I have a cup of tea in the holder, it just starts spilling over. So I don’t know how I can possibly imagine such things.
So now I need your help, if any of you ever faced the same issue, to advise me on what could be the cause, or how to resolve it or what do I need to check/replace.
FYI, things that I’ve replaced so far: spark plugs, engine oil & filter, clutch’s master & slave cylinders.
Thanks.

No I haven't tried it, but I'll look into it. Thx for the tip.
I was also thinking of taking the throttle body out, clean it & put it back on, or maybe replace the throttle position sensor if required. Do you think this can help?

But I thought this only applies to when the throttle body is bolted on my car, as this could chop my finger off, but if I completely remove it out of the car, then try cleaning it, then touching the butterfly wouldn't be an issue, right? Coz I have to flip it open, in order to clean around it as well

So what would be the safest way to clean them then? I mean it's a 2007 model (10 years old) & never had the throttle cleaned, so it surely need cleaning.
Or should I take it to a mechanic to clean it, instead of doing it myself?
Would cleaning it even help, or will it just be a waste of time? Any other thing can be done?
