I'm not sure if it was clear in my original post, but Dr. Bob actually authored the document. So, I've e-mailed Dr. Bob asking his permission to share or post the document. Once I get the OK, I'll post it.

Also, come to think of it, I wish I would have gotten Dave's SS replacement... If you're going to do it, spring for the extra couple of bucks.

PS - got pulled over today by a NY State Trooper for speeding, and actually didn't get a ticket!!! Whew!

The file is too big to attach here, a little over 1MB with the pictures included. Steve will post a link to his website here so you can grab it. If that doesn't work for you, send me an e-mail request at dr.bobf[at]att.net and I'll send a copy right back.

Does it have to be a "Y"?

Nick--

I was dreading the cost of a Porsche part for this, and looked around the hardware stores and even the boat yard bins for a suitable substitute. Found some at the boat bin. Then tried the dealer, and they were cheaper(!) there and they had the right part. Go figure!

Dave C has a stainless never-fix-it-again replacement that I should have bought but didn't. That's the way to go. When I did mine, I replaced a section of hard hose to unload the connector some, and tied all the hoses and the conector up snug so MAYBE it won't break again. If I loose one once every twelve to fifteen years, not that big a deal, eh?

A thank you to Dr. Bob and Steve for sending me the document. I think I am going to try it as soon as I get the part.

Worf....how do I get in touch with you to order the SS. Even if my Y isn't broken, it sounds smart to put the SS in anyway.

Would a broken Y connector cause any other problems besides smell?

My car seems to hesitate the first second of acceleration. I know I need a new air filter. I am guessing that I am not getting air to the engine. (There was a rodent nest in the air filter when I first go the car!) Otherwise the car runs decently.

Just want to know if the faint gas smell would have something to do with it.

Kevin, year of shark?

Hesitation can be caused by a bunch of things. But, I've never heard of a broken y connector causing hesitation.

Hesitation could be caused by dirty grounds, a faulty idle switch, intake leaks, 02 sensor, bad plugs or wires, low fuel pressure, etc. The place(s) to start looking for the cause depend upon the maintenance history and condition of your car. Oldest, cruftiest items are at the top of the list.

1983 huh? Ok so it's a CIS system. Nevermind what I wrote above - although it might be correct - I don't know nothin' about CIS systems.

Thanks worf, I'll be sending you an email soon. The hesitation isn't really that bad, so i'll take my time trying to diagnos.

Idle switch? MMMM...I am idling in park at 800.. In drive at stop at 250, which I thought was very low.

Does it have to be a "Y"?
I'd imagine a "T" connector would not allow the proper airflow since resistance where the air hits the "T" that's perpendicular would be much higher than the "V" opening on the original connector.

Now, if I could only find a document describing how to fix that darn cruise control...

Using a standard "T" I got at the hardware store is how I did it. At the time I did not have mr worf's fine SS piece, or I certainly would have gone that route.

Point to note. The hoses are not the same diameter, one is larger. therefore you would need a "t" that fits the smaller hoses, and build it up with electrical tape before you clamp on the larger hose. All I can say is, the next time I go in there T am going to have the SS piece ready to install. I doubt the "T" shape has any impact on its functionality......there is only a vacume pulled through the system for the first few seconds of operation. That is the only time it functions dynamically. The system is closed to absorb fuel fumes and at start up, is drawn into the intake manifold. After that initial action the system is static. This is the reason you don't notice an elevated idle when the connector is broken.

And, BTW, a broken "y" connector is a little bit like prostite issues in men, in that virtually ALL sharks have a failed one.................sooner or later........So the first time the passenger wheel well has to come out, it should be standard maintenance to replace the orignial y connector because it is almost certainly broken.
