I've had this happen twice in the last 20 years. First time the throw out bearing was knackered. Second and more commonly air in the line and the system needed bleeding properly.
I have heard of pressure plate drag also but never encountered it myself.
To be fair it passed so whatever the cause for increased CO2 I'm happy with it Worth the risk for the 25 extra horses after all the mods. I do need to spruce up the underside though as it's looking a bit tired. W brace refurb, new camber arms and some adjustable coilys next.
Not the HFCs mate its the richer mix. Car had HFCS new just before last MOT and I know they need to be hot. Car has done 4k miles since the previous test. Had a service a map and new plugs in between that's all. All lambdas were also replaced last year. I took it out for an hour before the test to get the cats nice and warm
Well it did. Only difference is the fueling is richer and the HFCs are a year older.
It was running to lean before the Uprev so my guess is the increased fuel mix upped the emissions.
Phew
After last year's excellent MOT emissions test I was expecting a slight increase this year as I've had the car mapped. Idle CO2 was great at 7% but fast idle scraped through bang on the 20% limit!
Also an advisory on a slightly corroded coil spring but that's good as I can now blag the other half I need to get some new coilovers
Great fun and educational, we did our training on a skid pan and in a modified Senator with a hydraulic scaffold and caster wheels to simulate under and oversteer. Ironically it was at Dunsfold many years before Top Gear started filming there.
That's the strange thing though, the 370 is also looking old as it's 7 years since its launch, however it's yet to be superceded . It's all a matter of perspective when a new model is released the previous one looks old. Looking in isolation at design though there are cars 20 years old that still look fairly contemporary because the language used is timeless.
Porsche still maintains the same generic look it had 40 years ago but because the design language is timeless not many would say the latest gen looks old.
The 350 is a similar looking body shape and I agree that certain design cues such as the facelift lights etc help to keep it looking contemporary.
I like them both, the 350z relaunched nissan as brand and is iconic for that. The 370z tweaked that formula and is just as good if not better in some areas. I don't think either looks dated as they are both a classic sports car shape seen countless times over the years.
All that lovely dense cold air and a sunny dry winters day, less roadside foliage better visibility. Mind you down south I've not seen proper snow or even major ice for years.
Adjust handbrake as advised and if the hand brake pads are in good order rough them up a little with some fine grade wet and dry paper.
My handbrake on 80k miles was shocking, whilst changing the rear discs I took the opportunity to do this. Three clicks and it's tight and secure now whereas before it needed to be pulled right up to get any engagement.
It's all about maintaining personal mobility in a future where roads will become more congested.As much as I hate the idea of automation, from a stress free non polluting viewpoint jumping in my little pod as an old man and popping out to visit someone on a wireless powered road network does have its appeal.
For now though I'm making the most of the combustion engine.
Let's not get carried away about EV just yet, its still in its infancy relatively speaking.
There is currently a certain demographic who buy EV and the majority that don't. Every mainstream car brand wants to appeal to every potential customer.
The flip side is of course the fact oil derived products will eventually run dry and manufacturers need to adapt as do we. Is the future EV, to be fair I don't know and neither I suspect do auto makers.
You can't possibly say it's the way of the future but the innovation is to be applauded.
I have only one criticism of the new RS and that's the seating position with the optional wingbacks. Far to high and no height adjustability.Im only 5"11 and if I leant forward my head cracked the sun visor
Otherwise it's superb
In the days before the dash cam I dropped my little FRP off for a full respray only to pick it up two weeks later with 500 extra miles on the clock!
Let's just say that after that my trust levels tainted a little
I've done one of these events before, totally knackered me out and I couldn't walk properly for a week afterwards. Well worth it though as I felt like I did as a kid when doing it, wet and covered in crud, awesome fun.
If anyone asks me if they can marry my daughter I'm going to wind them up a little bit first
If they don't ask that's fine as long as my daughter is happy then I'm happy.
Once you've had a drive let it idle then put the a/c on. If it stops doing it it may be a normal feature of the car. Mine on normal idle used to do this when warm as the revs fluctuated slightly and the knock could be heard around the gearbox area. Putting the a/c on means it ticks over at slightly higher rpm and the intermittent knock ceased. I've just had all my bearings and clutch replaced and it no longer does it.
This may sound silly but does it disappear at slightly higher revs e.g. With the air con switched on?
Is it very intermittent and sounds like the car is going to stall but doesn't?
