1999 996 coupe with 122K miles. P1124 and P1126 codes reappear after deleting and only driving a few miles. Car runs fine and no white smoke. I'm assuming that I have a throttle body leak somewhere. Thought it might be the valve that connects charcoal canister to throttle body. Attached a picture of the valve below.
My understanding is this valve would be closed at all times except when power is put to it. With a hand vacuum pump attached to either end of this valve, it will not hold vacuum. Should it hold vacuum? Could this be my problem? The vacuum bleeds off fairly rapidly. Thanks in advance for any help.

Might be better off posting over in the 996 forum.

I totally agree. My intent was to put it under 996, not sure how it ended up under 997. Now wondering is there a way to just move it?

Mods might be able to. I’d just go ahead and repost over there.
