R33 Skyline Start Up Problems In The Morning

[tripsteady]

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.

Ohhh right my bad, i get ya, sorry i dont use these forums much until recently. Thought the person who started the topic is in control of it.

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

[vh45tt]

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

[Godzilla1]

holding in the key longer did not work for me

[dyl33]

What fixed mine was either cleaning the throttle body or it had somthing to do with the cold wheather we were having now it is warmer it doesn't do it

[Savtraxx]

idle speed control motor is dirty.
