Got a problem with the idle speed on my saph.

It's just started to idle anywhere from 2-3k revs when hot?? When cold and during warming up it seems ok?

Disconnecting the valve when the problem starts seems to turn everything back to normal?

I'm not sure its valve seized though as its clearly doing something when its reconnected when hot??


The car has just been setup in march on a new msd chip and was running fine until yesterday

Anyone got any ideas??

Thanks, Ben
