Can you drive without the ISV

[Godzilla]

As title really. Just wondering if I can drive without the ISV, will it do damage to the engine? Its on an 8v Digi.

You mean delete it and reroute it?
Not recomended as it will always run like poo on cold starts.
Americans do this because its hotter and idle warm up is quicker!
Its been debated amongst the G60 lads as it aids the extra boost out to stop it damaging the engine.
Reroute kits is just a fixed valve with a loud whistle on the G60's?

Why by the way?

Mine suffers from bad idle, revs from 600-1600 about 4-8 times when i stop at a junction, roundabout etc, then settles down.....sometimes!  I un-plugged the ISV and all seemed ok except idle was very low but at least it was not hunting like mad!  Ive cleaned the ISV twice with carb cleaner with no joy. I read somewhere that you should leave it to soak in either petrol or carb cleaner for at least 2 hours.....not tried this. When you say re-route it, how would I go about this?

Best option is ring around breakers yards for a 8V MKIII and just fit it.
The re-route road, all that does is give you rough idle in our climate TBH.
Carb cleaner or petrol should temp fix it but if its knackard, then its knackard?
Check ther eis no break in wires to the ISV just incase its not opening the valve fully.
Don't mess around with the painted yellow screw on the end!
Taken from another thread I wrote.

 Take the ISV out and use half a can of carb cleaner on the inlet and outlets until it runs clear.
ISV get stuck all the time depends how much crap get in them. Or check the current whist reving up to 3000rpm three times from idle and check current for 420 +- 30mA also unplug the temp sender it should not affect the current if it fluctates its buggered!
