What's This/What's It Do?

I'm surprised your WGFV isn't rusted shut...or is it? ;-) Anyhow, double
check your Coolant temperature sender's contacts and clean them and coat
with dielectric grease as well. Another thing to (easily) check (aside from
the usual hose clamps and TB to IC hose, is that the BPV vacuum hose isn't
leaking. I'd remove it from both the manifold and the BPV, hold your finger
over one end and (attempt to) blow through the other. I know, is not
related to your problem (I don't think), but a good thing to check "while
you're at it." WMB has a silicone hose (red) that is perfect for this
potentially high temp application.
