So I get to buy a new one.
Where other than the dealership can I order this part. All the local auto part stores don't have it or can't even order it.
I think the Haynes is not very clear on this. The only way that the above will occur (Install a vacuum gauge to the EVR outlet port and using a hand-held vacuum pump, apply vacuum to the manifold vacuum supply inlet port. Vacuum should hold and no vacuum should be indicated at the gauge), is if you remove the sponge air filter on top of the valve and plug the line.
The question at hand is how tight of a seal does that sponge air filter need to create? Mine will not hold a vacuum and I can only make the Haynes diagnostics happen if I remove the sponge air filter on top of the valve and plug the line.
