Sounds like you might have a few vacuum leaks or a dead iacv. Is the cam timing aligned properly with all the corresponding crank and cam marks? It could be out a couple of teeth one way or the other.

Cheers

I read online that you can determine if the IACV is working or not by disconnecting it and comparing the idle. Apparently, if the idle stays the same the IACV is not working. In my case the idle has changed but disconnecting it seems to "fix" the low idle problem.




Not exactly sure where the vacuum lines are, tried finding a diagram but only found them for turbo engines.

Once my SG is warmed up, my idle is usually around about where yours is in the first picture. It does vary slightly. (Guessing because of aircon, weather ect) It did take me a while to get familiar with driving, coming from a diesel where you could take of without touching the accelerator. It is a little annoying getting the rpm up from low rpm as the petrol engine is less responsive. But I just see that rpm as normal idle and got used to it.

Is there any way to increase the idle without causing damage?

My MY06 is like Red's, and yours.

Once warmed up, idle is the same as your first picture.
