[T3] '72 FI won't idle down

[David]

[[[One thing I had to

do was put a restriction in the line to the crankcase breather, something

Ray Greenwood suggested, about 3mm, that seemed to work

And allowed it to breath but kept idle within range.]]]

I can see there’s a LOT of air going through the PCV valve, and I wondered if I somehow restricted the large diameter hose to the PCV valve - it would reduce the air entering the IAD…..thereby bringing down the idle….But that seems like a wrong thing to do to a ’72 system with large diameter fresh air hoses coming off each cylinder head. I put my finger directly over the PCV valve to eliminate it, (not that I would run it this way) and it reduced the idle speed a lot, but not enough to make it idle – so there’s some other thingy amiss.

Thanx for the props, John 😉
