Thanks for the tip.
I had been having the no start after fueling up with my 2000 boxster S plus irregular fast rough idle with cel error codes P0507 P1128 P1130 & P0446.

There is no emission testing in my area so I made a small clamp to clamp off the vacuum line .... worked great !!
No more rough or fast idle & car fuels up with no problems now.
Its been 3 days now with aprox 300 km driven & no cel or error codes yet.
