R33 Skyline Start Up Problems In The Morning


Recommended Posts

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.

this has been happening with mine as well, i have cleaned the AAC valve with little success. i am going to try the holding the key on longer tomorrow morning. With this action will it not hurt the starter tho? Thanks for this forum tho much help

    • Well I had 2 choices from then on. I either had to (reluctantly) move it on to another potential buyer and take the loss on the chin. Or I stick with it and turn it into a restoration project. I chose the latter. Project Snowstorm began! The frp body kit was the first thing to go. Turns out the original colour used to be silver. The Neo and gearbox were removed, along with the prop and exhaust system before it took a trip to the bodyshop, where I wouldn’t see it again for quite some time due to the pandemic hitting very soon after they took it away. Eventually, progress began and damage assessments made. Even the front chassis leg was in pretty bad shape!     Then the chopping commenced. For these guys it was just usual routine, to me it looked absolutely terrifying!   More to follow as I’m struggling to focus on my screen at 12:45 am!!!
    • That's the most absurd thing I've ever heard. I would go cut bellhousing over that monstrosity of a flywheel all day, every day. It puts a lot more mass further from the last main bearing. I've had nothing but problems with Collins in the past and refuse to ever buy their products again. I would not trust anything they tell you. He's playing his salesman card.  I'm currently at 640whp on a mustang dyno (~770bhp) with the intentions of running E85 and a lot more power this upcoming spring. Cheers, 
    • Nah, it's not the reduced knock margin. It is a direct mechanical effect of having to initiate the combustion earlier, while the piston is still rising, which starts to exert combustion pressure on the rising piston earlier, making the rest of the engine work harder to finish driving the piston up to TDC where the combustion pressure stops being a negative and starts being a positive. Your modern engine that only needs ~10° to make MBT doesn't waste the other 10 or so degrees of crank rotation. That's almost all of it. The difference in knock margin might go either way. Remember that modern engines to which you are currently comparing the long tractor engine (the RB) are now running super high compression, direct injection, tricky cam control and maybe even cylinder pressure sensors. You're not comparing apples with other fruit. It's apples and sea weed, or some other evolutionarily primitive vegetation. And remember, squish only really comes into play at the very end of the stroke. It certainly does good things, but it is not the biggest contributor to what's going on. It is quite possibly much less important in 4 valve head than 2 valvers also, because there is so much less squish available to a 4 valve anyway.
    • Food for thought, a longer stroke motor would need less ignition timing vs. a shorter stroke motor requiring more ignition timing.
    • Thanks Duncan, HART is only 10 mins from me (I did my bike license there), it'd be awesome if it ran these types of things.  Sutton Road does look good and they take fewer cars than SMSP which is good.  Surely you have enough land to lay a few million tonnes of concrete and some sprinklers D?
