So it worked for you too aye? Well i guess its good news we found the cure, but i dont understand why it needs that extra second. Atleast i wont have the dodgy start ups anymore. And i guess that aac valve didnt really do much in the end. Only way the aac valve would help the start up problem was if you increased the idle speed, which was getting rather annoying, hence why i returned it back to normal and done this little experiment ;p. Glad it worked your you as well!

picked the car up from paden , he adjusted something but was really strapped for time and had to get to work so didnt get to ask him what exactly.

he did also clean the aac valve ,and this morning it seemed to be fine , but will have to wait to see if the problem is solved

Ohh really?? Niceee, might be the idle perhaps?? Did you notice it idling slightly higher? As long as the problems gone should be all sweet =)

it idles a but higher but started my car this morning and it did the same thing. So i held the key in the start position for a bit longer then cranking and it worked!

as suggested previously this is the fix , but what is the cause?

In all honesty i have no clue what the cause is, at least we've sold the problem. Still would like to know why that extra 1 second determines whether the car starts like crap or not. Might ask the mechanic.

Anyways for anyone who does visit this forum, we just turn the key for an extra second while starting up in the morning and it solves the start up problem, however we just dont know what the problem is although we found the cure.

For some reason my car doesn't do it anymore.

Now it starts fine, little higher idle while cold, then goes to the normal 650-700rpm once warmed up, Then somtimes after stopping it idles high before dropping to the normal again.

Anyway cold starting problem is no more. fingers crossed

Just a note guys your TPS can cause this issue too. Tps giving a false reading when cold makes the af ratio go way rich causing idle and stalling problems. Test your tps with a multi meter. Its not an issue when the engine is warm as the warm engine can cope with the richer mixture.

      There are adaptors that allow you to delete the booster and use an s15 clutch master cylinder.    if you want to keep the booster they are still available brand new

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I visited again today: It would appear they have painted the main body of the car and some parts of some of the panels, so I can say that I now have BMW parts in my car, much to the envy of @Dose Pipe Sutututu It is still covered in dust which is quite the tease but I did look at a few circumspect spots that will be behind bumpers and such and wiped some dust away: After my repeated begging to PLEASE DONT PAINT OVER THE ENGINEERING CERTIFICATE (you have to re-engineer the entire car if they do) I see THIS: Which is great. Excellent job tbh at least to me. A better non dusty example would be the backs of the doors that have been painted: Giving a reasonable contrast between old and new (I know the old isn't clear coated on the inside of doors). The door card will well and truly cover where the old paint is, you can see in the second pic some of the black butyl/whatever shit is sticking the plastic sheet behind the door transfer that has happened since it's clearly been stuck back on. The most maddening thing about this colour is every time I saw it in the wild it looks like another colour, same with photos of many cars with the same colour looking wildly different in every photo anybody ever takes and this is no exception. But stand a little further back and it suddenly looks dark AF. I did tell them when I was discussing which of the 70 million charcoal colours to choose from (a porsche one, a BMW one, or a R32 GTR one etc) that if they just ignored me and chose one at random I would probably never notice. Maybe they did. But the colour is supposed to be B39 (BMW Mineral Gray). Boring I know, but the R34 sedan (to me) really shows off it's boat-ness when you paint it in a bright colour like bayside blue or white or whatever else. I do have a fondness for AR2 Nissan Red, but decided against that because it'll have pretty odd contrast to random bits unpainted (like engine bay, bits of trim etc, and maybe it'll fade). And people will always fkin comment on AR2. Everything remains super dusty. I have tracking numbers for the new heads, as well as some Improved Racing goodies, but they probably will be a next year thing by the time they end up on the car. I did some maths on the heads and I know why nobody goes to this extent in Australia, because it's really not worth it, given I could have just CNC'ed my current heads, bought a FAST102/TB and used my current rocker/spring/cam combination and get a 383 stroker (or stroked a 6.0 GenIV bottom end to 6.6L) built for the same price of just the setup in the mail/on the floor here. Or I could have bought a LS3 and a Drysump system. And then have a complete engine to sell. Oh well

      We just disconnected the vacuum line if I remember correctly, booster is still there. Is there a rebuild solution for the booster or a different adapter that will work for GTR chassis?
