    Hey Andy

    Thanks for the tip, isv definitely is working as when I connect
    The plug and make slight contact you feel the engine change. Haven't checked the N75 but that would be my next call if all else fails. Thanks for the tip!

      Update on this.

      Replaced the N80 emissions valve, the water temp sensor at the back of the head, PCV valve, crankcase breather valve, fixed some vac leaks at the back of the head also. Car is definitely pulling so much cleaner than it was even off boost but still won't happily hold idle with the ISV plugged in.

      Also boost is still cutting, I am going to change my MAF for an old unit I have lying around. Any pointers guys? Open to suggestions

          Yep, sorted as above, cleaned the MAF and it started to come to life. Decided to put the old one in and presto all is well. Car is running better than ever now since I also fixed a few leaks at the back area of the head and with the new sensors. Super chuffed pulling like a train . Thanks for all the help guys
