seech Posted April 13, 2011 Share Posted April 13, 2011 Apologies if this has been covered before - I have had no joy searching... At low traffic speeds in 1st/2nd, when you accelerate forward does your car bounce/jump a little making it appear as if you have made a poor gear change? It can be a little annoying and appear to passengers that you can not change gear! I have noticed the rev needle bouncing around too - but an early post revealed a possible cause which is not linked. I will tell Nissan to sort it (goes in on Friday). Thank guys Quote Link to comment Share on other sites More sharing options...
andyvvc Posted April 13, 2011 Share Posted April 13, 2011 One of the following might help, i had similar issues with my 53 plate years ago: 1 - clean the throttle body housing and butterfly valve (be gentle with it!) 2 - do the TPS (Throttle Position Sensor) reset thingy 3 - clean the MAF sensor 4 - Refer Nissan (if under warranty) to steps 1, 2 and 3 Quote Link to comment Share on other sites More sharing options...

James B Posted April 13, 2011 Share Posted April 13, 2011 Mine does the exact same thing. Only in my case it's my cack footed gear chaging! Quote Link to comment Share on other sites More sharing options...

daveparkin Posted April 15, 2011 Share Posted April 15, 2011 Hi Seech, Did you get anywhere with this at the stealers today? Let us know what they said. Cheers, Dave Quote Link to comment Share on other sites More sharing options...
seech Posted April 17, 2011 Author Share Posted April 17, 2011 Well. First of all, Nissan gave me a 60 plate Micra as a courtesy car. However well equipped, it's not a good replacement for a Z. Lucky the mrs has just taken delivery of a C250 CDI Sport. Otherwise I would be in a bad way. Anyway, Nissan called me and told me that they would look at the bouncy car/rev counter after they looked after the main issue - the juddering at high speed. It was not the balancing of wheels, as previously thought, it appears to be a dicky flywheel. Need to wait till Mon till I find out about the other issues...

daveparkin Posted April 17, 2011 Share Posted April 17, 2011 Thanks for the update - please keep us posted! I know how you feel with the micra. Was it the new 3-cylinder one, its almost like half a zed engine according to some dealers - they must have made a very coarse 2.0 litre zed at some stage without any of us knowing........................

andlid Posted April 17, 2011 Share Posted April 17, 2011 Flywheel can cause judder taking off if its not balanced. Can also be the clutch itself, then again... Nissan knows best Quote Link to comment Share on other sites More sharing options...
seech Posted April 18, 2011 Author Share Posted April 18, 2011 Do Nissan know best though? I fcking hope so! They said an engineer took the car out for a drive and that's how he came up with the diagnosis. Although it's funny how he did this without travelling over 70mph (say Nissan) - yet the problem only occurs at 80+... They weren't too specific on the details, hopefully I will have more info today and I will post it up. I have to get this Micra off my driveway. It's ruining all the street-cred the Z built up. 1.2 litre 3-cyl. Described by Jason Plato on last week's 5th Gear as "a turd". The only good thing about it is the brakes. They will stop the car on it's front two wheels leaving the back two 6 ft in the air. On a side note, does anyone know if the BT phone system should be coming through all speakers (a la Micra) or just the driver side? Can't seem to change it.

docwra Posted April 18, 2011 Share Posted April 18, 2011 The only thing that would affect a flywheel like that is a manufacturing fault Id have though - part of it has dropped off or as mounting has come loose, but Ive never heard opf that happening on any car. My money would be on the clutch as its 100 times more likely to have an issue, and they will be checking that when they look at the flywheel Quote Link to comment Share on other sites More sharing options...
Chris`I Posted April 18, 2011 Share Posted April 18, 2011 Flywheel is a dual mass affair. After enough miles the dampers between the two masses become ineffective and they start to knock together. Plenty of people have had this around 50k miles but swap them out for lightweight flywheels or new dual mass when swapping the clutch. That could be the problem.

seech Posted April 18, 2011 Author Share Posted April 18, 2011 OK. The latest from Nissan is that they think it is the flywheel. New flywheel on order, arrives tomorrow. Seems an odd thing to go at just 23,000 miles, but if it sorts it, then great. The bouncing rev counter > they think that will be solved too, as the crank position sensor is in the same place (so they say) and the vibrations from the flywheel could have knocked this out of kilter. The bunny-hopping at low speeds > they assure me that this is a characteristic of the car. Sod knows. No one on here seems to suffer so not sure on that one. The suggestions on here were along the lines of checking the MAF sensor/throttle body housing/throttle position sensor. Nissan say everything is reading completely fine/within range. That only leaves the excessive fuel consumption. Subjective, I know, but it does seem like it drinks more than others on here. But again, if the sensors are reading within range (so I’m told), then it should be about right. Will get a further phone call tomorrow to hopefully ask me to pick her up and return Nissan’s ultimate track-weapon – the triple-cylindered Micra.

Cant say Ive ever noticed it And a flywheel failing after 23K is poor, very poor IMO Quote Link to comment Share on other sites More sharing options...
seech Posted April 20, 2011 Author Share Posted April 20, 2011 The latest saga... Got the car back yesterday, noticed that the very low speed bunny hopping had gone. Great. Got on the motorway and the car was still fcking shaking. They hadn't even bothered to test it once the work was complete. It got me thinking. If the flywheel was knackered, it would vibrate at a certain rpm, say 5,000. So every time I hit 5,000 rpm, it would shake. But the problem is at a particular road speed, not engine speed. So that was never going to fix it. So it is either (I think): Dicky tyre(s), unbalanced wheel(s), unbalanced prop shaft. As the warranty I have from Nissan is a 3rd party extended warranty, I am going to see if I can take it to a specialist (you know - the people who know what they are doing) and see if they can sort it. Sick of it now. And I am not driving a fcking Micra courtesy car again. Quote Link to comment Share on other sites More sharing options...
daveparkin Posted April 20, 2011 Share Posted April 20, 2011 Your saga got me thinking................. ...........I've got a 313, too, and mine has done the low speed jolt/bunny-hopping ever since I have had it - it occurs as you open the throttle, for example as you turn into a side road off the throttle and open it again. I have been fed all of the "they all do that, sir" lines from the dealers, too! So tonight, I decided to do the 'throttle pedal released position reset' and 'throttle valve closed position reset'. It seems to have completely cured the jerky throttle response - its like driving a different car! Could it be that the dealer has done the reset procedures above to your car, and that is why the bunny-hopping is better? If your vibration is road speed related, not engine speed related, it seems very unlikely to me that it could be caused by the flywheel, or the clutch for that matter! I think you are probably on the right lines with wheel/tyre balance, prop-shaft, rear axle etc. i.e. something after the gearbox, but maybe they should also check the gearbox itself. Good luck and keep us posted! Quote Link to comment Share on other sites More sharing options...
350flash Posted April 23, 2011 Share Posted April 23, 2011 I know this an old posted message, but I have the same problem with my 2007 Zed. I took it into my local Nissan dealer to check out the jitters, and he says he could find a fault. It almost feels like it has a dead spot on acceleration and causes the car to jitter. It makes pulling away in first quite difficult as it jitters so much. Do you know what the problem or the solution is yet please. Quote Link to comment Share on other sites More sharing options...
350flash Posted April 23, 2011 Share Posted April 23, 2011 Sorry spelling error in previous post. The Nissan guy couldn't find the fault. Quote Link to comment Share on other sites More sharing options...

daveparkin Posted April 23, 2011 Share Posted April 23, 2011 350flash - is your car a 313, too? Quote Link to comment Share on other sites More sharing options...
350flash Posted May 3, 2011 Share Posted May 3, 2011 It's a 313 and I also noticed that the revs run higher than normal too as mentioned in previous posts. When you rev her up, it takes a while for the rev counter to drop and seems to pause a little just before it reaches it's resting position. I am embarrassed to say that I even stalled it 2 days ago when pulling away at traffic lights in 1st gear. The revs do weird things and it doesn't seem to know whether it is coming or going. I aim to take it into the local nissan garage this week or next before the warranty runs out. Quote Link to comment Share on other sites More sharing options...
