I think the car will be just fine without the AAV. Without the AAR you will get that popping and rough idle when starting from cold. Only you can determine how much of an inconvenience that is.

It seems that someone was thinking about installing a hand throttle on one of these later cars. Maybe someone can advise you on this, or you might find it in a search.

I think my AAR is not opening enough when cold, giving me a only a slightly raised idle. I am going to check the opened end next time it is cold, and see how far the valve has rotated. It should be open about half way when cold, then close off gradually.
