Hey Everyone, Happy New year and holidays!
I just wanted to update you on the issue. The new ISCV valve has finally arrived and the thing I was afraid will happen, happened again.
Upon swapping the ISCV with the new part and turning the ignition key to the on position valve again please check the video bellow.

Notice how after the fuel pump noise I switched the key to the ON position and the valve springed out off place.
I would appreciate if someone could measure the values on their ISCV using the multimiter when the ignition is switched to the off and on position, without the engine running so I can compare it to mine. I am afraid there is something wrong with the ECU and it’s providing the ISCV valve with bad current/values.
Thanks!
