Idle speed

[Richard]

Hey Guys, what is a good Idle speed? mine is sitting on around 1500rpm, I reckon this is way to high, how do I adjust it? move TPS?

there should be a screw on the inlet manifold which you can turn.

set it to about 800rpm and u should be right!

Its the BISS (Base Idle Speed Screw) screw on the throttle body......

Thanks to www.VFAQ.com for the pics.......

just remember to earth your timing pin and also your idle speed pin... (disable both) then adjust your idle to 800rpm, make sure its warm and once its stable disconnect the earthing wires and it should be good provided the idle control is still in working order

What do you mean by this and what will happen if I just turn the screw? mine is a 4G39T so the pictures arnt correct but I think I kno the screw on mine.

i think you need to do it so the computer isnt controlling it anymore, and you can set it to where you want it to be, and then once you take the ground away, the computer senses the new position/controls the idle speed? Something like that i think?
