No probs! I used the 08 service manual available here http://www.nicoclub.com/FSM/350Z/coupe/2008_Coupe+Roadster/EC.pdf (page 76) but in short you need to do this: 1. Start engine and warm it up to normal operation temperature. 2. Set shift lever in neutral position and confirm that following electrical or mechanical loads are not applied. - Headlamp switch is OFF - Air conditioner switch is OFF - Rear defogger switch is OFF - Steering wheel is in the straight-ahead position, etc 3. Keep the engine speed between 1,800 and 2,000 rpm at 20 seconds. It's pretty simple though I found holding the revs constant to be quite difficult. On my car the revs hunted around a bit despite the pedel being held still though maybe that is the calibration in progress. I found it best to get to just over 1800 RPM as it will rise slightly before falling again. I turned the engine off after performing the above and then restarted and went for a test drive. I did this last night and the difference was very noticeable straight away. I did a cold to hot cycle this morning driving to work and it continued to behave itself. Hope it works for you!

I seem to have fixed the hesitation issue on my car! I performed the Exhaust Valve Timing Control Learning procedure and now the performance at low revs, especially going into second gear is much better. I haven't seen any reference to this procedure on this forum but I found it in the service manual. From reading some of the threads on an American forum it seems some people think that the mechanism can be affected by different engine oils. The dealer who sold me the car did a mini service when I bought it which might explain why I didn't experience it on the test drive. My rev needle movement has improved but it's still a bit jerky. Time to get the tools out this weekend I reckon!

Ok thanks for all the info everyone. I'm quite happy tackling jobs on cars, have done quite a bit in my time though I guess all of the scary stories around the throttle body has just made me nervous. I'll get in there sometime over the coming weekends, and then try the MAF sensors too if there is no improvement. The Uprev remap would be nice but I'll have to save a few more pennies first! Btw I have discovered that the plugs have never been changed so I'll get that sorted soon with a major service.

Haha yeah I'll try and keep my eyes on the road instead! Yep throttle body clean could be in order though a bit daunted by it to be honest especially as I've got two of the buggers.

I do get a bit of hesitation when in low speed traffic in 2nd gear, probably around the 1k to 1.5k RPM range. I don't think the plugs have ever been changed, though I'm still waiting to find out from the Nissan dealer who did all of the servicing before I bought the car. I guess it could be that a proper service is in order.

Hi jimboy, yes I've done all of the possible resets but it didn't help at all. Still, can't be any harm in doing them anyway! Thanks for the reply though, just knowing that yours doesn't look like mine is helpful in that I know something is wrong.

Ok I know there have been various issues around the tachometer but I think I've got something different going on here. I've scoured the forum but apologies if it has been covered before. I've had the car a few weeks and thought I'd noticed it on the test drive but put it down to paranoia. But it seems to be getting worse. Basically the motion on the needle on my rev counter isn't smooth, it seems to move in jumps especially in the first 1/3 of travel. I'm not talking about the jumpy needle upon changing gear which I know quite a few people (including me) have, or the needle sticking completely like some Roadster owners have suffered in sunlight. Here's a quick video of what I mean. It's actually more noticeable when driving but you can see it in this video mostly when the needle is falling. It doesn't seem to correspond to the engine revs. The "pause" as the revs fall past 1400 RPM I think is also another issue which some people have experienced? I'm thinking obviously the counter mech itself, the engine speed sensor or least likely an ECU or wiring issue. I guess the engine speed is detected from the crackshaft angle sensor which I think is located next to the flywheel? It's an HR. If it's just the counter then no big deal though this car is still under a warranty so I should be able to get it sorted. If it's the sensor then I'm more worried about it affecting the performance of the engine, though I have to admit it seems to drive fine. Maybe a little rough at very low revs though I suspect it still has the original plugs in there, trying to find out at the moment. Sorry that went on a bit - any comments or suggestions welcome!

That's exactly what I'm after. Time to start hassling them then, I've only sent an email so far. Thanks! I managed to get a computer record of all the history of mine from the previous Nissan Dealer (effectively a printed version of all the service invoices)...Scott at Abbey Motorsport knew who to talk to and got it for me. It was a lot more helpful than some stamps in a book when I came to sell it.

Haha small world, I haven't seen you about. If you ever saw a silver Mitsi FTO with GPvR spoiler around these parts that was me! I shall see you around Stockwood then í ½í± gf lives there , you will see my zed up there somtimes í ½í±Œ Sent from my iPhone using Tapatalk

Sounds good. I'm not gonna be able to make this one but I'll keep an eye out for the next! http://www.350z-uk.c...iew__getnewpost

Well I was leaning towards a Zed but the divider clinched it! Cheers guys, PM's received and replied to Does this mean the dividers are so awesome, that folk are now just buying 350Z's so they have something to fit it to?

I wanted one before I got the car too, PM on its way!

Thanks for the welcome guys! It's black, one owner, had just under 30k miles (not any more hehe) on the clock. I'll get some pics up soon. I'm in Stockwood, South Bristol. Btw the reg is MW57 SWJ the original owner was around Oldham way. It'll be interesting if anybody on here knows the car. It's been Nissan serviced throughout and I've been trying to find out from the dealer up there if any of the optional service jobs (plugs etc) have been done. Do the Nissan dealers keep a record of that? No response from them so far.

After admiring these cars for years I finally picked up an 08 HR 350Z a few weeks ago and I'm loving it! Coming from 200 BHP at the front to 300 at the rear has been quite a change! This seems a great forum and it has helped me loads even before buying the car so this post is just to say hi and thanks to everyone. I've got a few issues with the car but I'll leave them for another thread!
