Yes, you could do that, but in the original installation it is 
powered in parallel with the fuel pump, so it doesn't heat up unless 
the engine is actually running.

Those are important as far as getting the right gas mileage goes, but 
none of those should cause bucking and missing if they get a bit off 
spec. There's something else behind that, and I don't think we know 
what it was yet. I'm still considering the possibility that the CHTS 
was intermittent, but that finally heating it up to full temp with 
the vibration of a running engine wore thru whatever corrosion was 
causing the intermittent internal connection. It's just a theory....
