Do most 350s out there have ASD? Most I see here don’t have it. But I agree it’s poorly designed because it’s dufficult to bypass when it stops working properly.

They have that stupid vacuum wastegate for one, several of them seem to have the ridiculous ARV in the turbo outlet, different prechambers and injectors (which are actually a bonus in this case), I'm sure there's other things too. More vacuum gadgetry = more headaches.
It seems like a lot of the '91 350s have ASD. Not sure if they made it a standard feature right before they discontinued the car or what. '91 was a weird year with a bunch of 350SDL exclusive parts and options.
