The purpose of this forum is to help anyone who is trying to stop those pesky vacuum leaks and can't figure it out.
My 73 1.7 was having high idle issues. After replacing all the vacuum hoses plus the intake hoses and manifold gaskets, the idle was better but still at 1200.
I was looking at the air filter box where it inserts into the air box. I squeezed it with my hand while running and the idle went down to 900!
A quick trip to Home Depot for a large hose clamp and my teener is sounding mighty purdy!
I guess over the 39 years the connection seal was not the same as new.
Hope this helps anyone who may be experiencing vacuum leaks and high idle.

Terry, there was originally a hose clamp there, and someone left it off.
Terry - question for you - I'm about to replace all my vacuum hoses as well, did you happen to note how many feet of each diameter you used? Asked this question before and there did not seem to be a consensus - I'd like to order the right amount of each diameter before embarking on this - just asking?
thanks - td

Jamie,
I am the original owner of the car and I have never seen a clamp there! The first 60K miles my teener was serviced by my Porsche dealership. You would think they would recognize the problem! Go figure!

Right on. There's suppose to be a clamp there. Mine had one. Too many beers at the factory.
