    Temporarily Plugging N80 to diagnose possible fuel air trim issue... safe or not?

    Is it safe to plug the N80 valve and then run the car any distance. I'm trying to diagnose a fuel/air trim issue that I mistakenly identified as an immobilizer glitch (link below). Clamping the line helped mitigate with my starting issues but I want to check that it runs okay during and after warm-up too. Will I cause more issues running with it clamped? Will it prevent me from doing any effective diagnosis?

    That is the evap solenoid so you'd likely be fine.
