Sup Everyone,
I was wondering about my cold idle when i go outside in the mourning for work and its been pretty cold outside the Rpm's go to 3,000 and stay there. I know thats not really safe but i was wondering what could be wrong? Thanx alot for any info peace.

Are you using the VE throttle body? If so, you can adjust the cold idle.

Sup,
Yea it is the VE TB. Is the idle screw on the back of the manifold because there isnt one on the front anywhere and i know the AAC isn't for that. Peace

idle adjust screw is behind the vc, above the injectors.

I believe you are talking about the idle screw on the AAC, he needs to adjust it on the throttle body.

oops. after re-reading, of course you're right on.

You guys are wrong on this one. If you are using the VE TB the cold start idle is adjusted on the TB. The tubes that run under the TB run water into the device under the TB that self adjusts the TB with water temp. When cold the plunger pushes out to open the TB when hot the plunger goes in and that close the TB to reduce the idle.

i have a spare ve tb if u need it..

Andreas Miko · 11-27-2005, 06:26 PM

It should not cold idle more than 2000 RPMs. It will not cause a problem but its should be lower and can easily be adjusted to do so.

I will idle proper when it warms up because the TB will shut completely when the temp reaches normal oprating temp no matter wher you set it to idke at when cold

I agree w/ Andreas. You should adjust the little plunger to the bottom left of the TB when looking at it. He posted this info about 2 years ago (that I remember). I bet a quick search would give about 5 threads regarding it.

The little "screw" has a nut to lock it in place and then you need a pretty small allen head to adjust it.

Sup,
THanx guys for the info, i am going to adjust it because i don't think its the best thing for the car at startup. I haven't looked at it but is it an idle screw or is it something else i have to adjust? peace

Please note to get the right TPS reading and cold start RPM you will be back and forth with the 2 because you are rying to get .44-.50 at warm idle. So set you cold start first then go and set the TPS once the motors is warm. What I am saying is the cold start affects the TPS reading because it moves the TB plate as you adjust it.

Here you go.

My RPMs shoot pretty high too - I should really try to adjust this - My VE idles very high -

Cabin03 · 12-02-2005, 11:57 PM

But when my car is warm the idle stay at 1200 rpm anything wrong ???
how can I adjust it

jer_760 · 12-03-2005, 12:07 AM

You need to adjust the base idle on the aac.

I used to have this issue of it idling at 2,000 or more rpms from a cold start. Soon as I got a JWT ECU it fixed this problem. Not saying this the fix-all, but it worked for me without having to adjust the TB.

Been wondering about this issue too... Idle is fine. Just cold start idle seems a tad high. In the 2k region. will asjust on the TB tonight. Also don't think it's good for the motor to idle that high when cold after reading HPRO's threads on 0W oil not even lubing the motor properly when cold....

BEAST · 01-24-2006, 01:35 PM

my ve idles around 1200... warm up is about 1500, so thats not too high and sometimes when im on the road the ve sometimes idles at 1000-1400. I adjusted my acc valve and the screw cant go no further... its screwed all the way down... i believe it is a possible air pocket somewhere in my cooling lines...
