or leaky injectors.
i also found leaky intake gaskets floods the engine with coolant after sitting a while running.

I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.

Re: VX L67 with 69mm TB Cold start stalling
The original problem was that on a completely cold start it would stall. 99% certain it was related to the fact that I am using a VS TB on a VX which has a larger IAC stepper motor pintle/passages. Got around it mostly by using the VS SC settings IAC settings although we never really figured out which settings actually controlled the IAC stepper motor decay rate.
The current issue is the weird noise which I'm 99.9% certain is been caused by the IAC. Happens mostly as the engine is returning to idle, just above idle, can't seem to re-create the noise sitting idling in the driveway with the transmission in park.

Re: VX L67 with 69mm TB Cold start stalling
exactly like a belt squeal but it's not. The weird thing is it can also be heard through the exhaust.

at the tailpipe?
According to chemistry, alcohol is a solution...

Re: VX L67 with 69mm TB Cold start stalling
Impossible to say as I can't recreate the issue with the vehicle stationary unfortunately. The changes I made yesterday has seemed to have reduced the noise somewhat though.
Going to try a different stepper motor tonight when the missus comes home.
