MANDALAY · 03-02-2008, 04:57 PM

Is there any adjustment on the Idle control valve ?

Thanks ,thats what l thought.
Lightened flywheel makes idle a bit more jumpy.
Sometimes stalls . Need to make it idle at 950 rpm.

Cool

It's self adjusting, should idle properly regardless of flywheel or not.

You got the speedo signal hooked up to the ECU?

MANDALAY · 03-02-2008, 07:30 PM

I assume but then again ?
What pin code and number is it and color ? Mind you i have the Beams engine and body loom.
I can see it tries to adjust but if it dips to 500 it struggles unless i accelerate a bit.
If i dle at 950 set it can sometimes dip to 650 but recoverees.
Could it be that the light wheel lacks the inertia

Also on the inlet manifold closer to the throttle body underneith there is another entry for a hose which is no bigger than 1 eigth of an inch in diameter and inch long . Manual says to put a rubber stopper there ? Anyone have this hooked up differently ?

Ok hope this doesnt sound like witchcraft.
Just changed my engine oil, used the same one Toyota 10/30 w VVTi
and gear box oil but using Red Line 75/90 NS and guess what no idle issue at all.
No stalling and rock steady idle @ 850 rpm. Now i didnjt touch anything, Can anyone explain ?

Well how long have you been running the motor for? Perhaps the idle was still 'finding its feet' so to speak, finding the right point to get a steady idle.

MANDALAY · 03-05-2008, 06:22 AM

The engine had done 1,000 kms.
All the time idle was a bit bouncy with sometime stalling. But as soon as l changed the oil , presto , no bouncy idle and no stalling at all. Weird.
But Roman l do agree with you , logical answer , just weird coincident to happen just after l changed the oils.

it is witchcraft

mine had some similar issues

mr220v · 03-09-2008, 09:27 PM

Had my manifold off the other day, and the idle control valve can be swiveled a little bit.

Idle sweet. Cant explain it.

MANDALAY · 03-23-2008, 06:59 AM

Explained ! No witch craft involved the clamp on the hose coming from the inlet manifold to the brake booster was not on . Must have been a very slight vacuum leak even though the hose is on very tight.
