Hey all, my R33 GTST switches off while driving- say when i am approaching a red light- when i go from 5th gear to neutral- the car just switches off. the rev meter quickly goes down under 1000 and engine stops, this doesn't happen when i don't go neutral- but still this should not happen, right?

also when changing gears upshift- if i am show in changing gears the engine will stop, say changing from 3rd to 4th- the moment i am on neutral, the rev meter quickly goes down, and if i don't change the gear before it goes under 1000rpm, the engine will go off...

it's scary when it happens in corners, coz the brakes harden and steering locks..

Any HELP will be appreciated.

I'll second the aac valve.

Mine's been doing exactly what you've described.. my mechanic said mine's stuck and I need a new one so I'm trying to find a second hand one at the moment without any luck. Might call nissan in the morning and see...

well ur mech doesnt know what hes talking bout.. its behind the plenum on an rb25.... its got 2 electrical plugs and a screw on the back that controls the idle. turn the screw clockwise to get more rpm on idle and anit clock wise to get less. try taking it apart and checking the spring inside as they break very easily. also try cleaning ur throtal body.. ps this will be ur roblem if the car will idle when its cold..... the aac valve works only when its warm.. when its cold the auto enrichment kicks in... good luck... u got email.. ill email.. u some pics

      How old is too old for tyres?

      By Murray_Calavera · Posted

      If the tyres were fitted when new, I wouldn't expect much over 5 years of use. Especially if the car lives outside full time.  If the tyres had been stored under ideal conditions and are being purchased new, I'd fit a set of already 5 year old tyres if I only expected to get 1 to 2 years of use out of them.  I've purchased many a set of new (but quite old) tyres from St George Tyres when I just needed some decent rear tyres to drift on.  Here is a pretty crazy example, can't say I've ever bought 11 year old tyres from them before though lol.  https://www.stgeorgetyres.com.au/momo-tyres-245-45-17-outrun-m3-official-product-by-momo-italy.html

      Also, a tip for young players  Check the dates on new tyres before they fit them, I always ask this question at the tyre shop, as they have tried to put "new" tyres on one of my cars a few years ago, but the build date was about 3 years old

      Yeah - 4 or 5 years is the limit for decent tyres. Pedestrian grade tyres with 400 TW ratings start out hard and don't start to suffer until they are somewhat older again. But the stickier decent stuff? Nup. My current ADO9s are < 2 yrs old, 17000km in, only have about the minimum 2mm of tread depth left, and they are.....not what they used to be. They are clearly much harder now than when new. Whether that is heat cycles (unlikely, for a road tyre), different compound between top and bottom of tread, or actually aging out (in less than 2 years!!!) is not really able to be discerned. But I'd credit actual aging as being at least part of the cause. I've got an old pair of ~50% worn AD08Rs in the shed that I really need to get rid of. They started feeling waaaay too hard to put back on the car after a couple of years sitting there.

      Personally I wouldn't put tyres over 4 or 5 years old on any of my own cars. Once they go hard the grip characteristics completely change. As per most things it only matters in an accident and that's when you most want them to do their job!

      I'm replacing the front tyres on the E39 tomorrow because one of them has a few gouges out of it. There is so much tread still on them but they're also 9 years old and the rubber is super hard.  This falls within the guidelines of 10 years old that I've read which surprises me given their condition.  I'm curious about whether you guys care about tyre age or just judge the tyre based on condition? How old would you consider too old?
