Are these two different things or the same things with two different names??? if that makes sense???
If they are two different things where are they located under the bonnet. cheers.

 

Anyone? I've done a search and can't find an answer?

 

???

 

Here's a wild stab in the dark but it's probably the Idle Control Valve or the Idle control valve Solenoid ... for a bugeye owner like me it's the wildely expensive bit of kit which sits in front of the intercooler in the manifold

 

£250 for 1 off these bad boys from the stealers

idle control valve... iscv idle solanoid control valve

 

Idle Control Valve, Idle Speed Control Valve.
One and the same thing.

 

or in Subaru workshop manual speak Idle Air Control Valve. All the same thing - bypasses small amounts of air past the throttle plate to keep the engine running right with the throttle closed ie. at idle.
