Working on the Alda and manifold line, I just discovered that the overboost switch (I think that's what it is--on the firewall, with a line in from the ALDA and a line out to the banjo fitting on the manifold) is not working at all. The inlet from the manifold was totally plugged, and I can't seem to get it cleaned out.

I hooked the two tubes together, bypassing the switch, and the car runs very significantly better.

Is there any danger in running the engine without the overboost switch, until I can get a new one? Or is the switch repairable--I can't find any way to take it apart.

I seem to recall someone saying that they permanently bypassed the overboost switch. True?

Advice would be appreciated.
