Hi guys. I have a strange issue that i originally thought was induction noise at idle.
The noise is like humming through a downpipe and obviously stops once the ignition is turned off BUT if i turn the ignition back on (without the engine starting) the noise starts again but dies doen after a second or two.
Has anyone else experienced this?
Im thinking it's maybe a solenoid opening back up while the engine is still under a slight vacuum.
