My 3.0 V6 has a poor intermittent idle when starting. This clears when warm and running.

I changed the Idle Control Valve after checking hoses etc. But problem persists

Then noticed that the idle is poor when there is a wining noise coming from the front passenger side of the car. Underneath the bumper and floor tray.

When this wining stops (sounds like an electric pump) there is a popping and what sounds like the release of air. Like a compressor finishing charging something up.

Following this, the car idles fine.

So what is causing this problem? That when it finishes, the car idles perfectly?

I am lost!

Many thanks

Andy

SAP running or AC Pump?, what happens if you switch AC off?

Check rubber hose from SAI not split

Thanks guys.

None of the hoses appear to be leaking.

AC is off and it still happens.

There is what sounds like a motor running then clicks and a expulsion of air.

Any thoughts?

Cheers

Andy
