The "distributor spark thermal advance vacuum switch" (that's what my '78 service manual calls it) that originally sat in the intake manifold cross-over on my '78 Trans Am was broken off when I got it and I just installed a temp sending unit in this location. The car seems to run ok withoutit, but I'm wondering if I'm missing some performance and should replace it (and find the necessary vacuum hoses that go with it). Any thoughts would be appreciated.
Thanks for a great forum. Steve
