Think I cornered the market on these....lol
PepBoys has the best "Help" section IMO. They have way more of a selection than AutoZone and Advance Auto. Ended up going to three PepBoys to get the rest of the connectors.
Did a cut on two and they fit perfect. There is also some flexibility with these connectors in that the attaching tubes can move to accommodate their final attachment.
For anyone that will have the need to address the original connector in the future, IMO these vacuum tube connectors should work just fine...

I own the market on these....

the cut...

fitting good...

lines fit very tight & snug....no reason to come loose....

Thanks Phil....yes it is an OEM alternative.....lol
The only thing that I have concern about is how well these will hold up with the engine heat. As the original connector is thicker in the elbow and again the "new" ones are more pliable, which is not a bad thing...
I guess I'll find out in time!!! lol
I could spend a lot of time under here cleaning everything, but if I do that I won't be driving the Z soon.....just cleaning what I can get to....

I also changed out the vacuum reservoir. I have a few NOS replacements, so I thought why not change it out....while I'm in here...

reservoir removed....area needs a clean-up...

cleaned and looking better than before....

new unit in.....

Yun,
I found the problem apparently the smoke test was correct. I don't think I have an intermittent vacuum leak, rather it is indeed the primary blade. The TB bypass may be an option for me in the future...I will probably need your expertize for that mod as I know you have something different that you do from reading previous threads.

Did the light test recommended by G8nightman (George) with a flashlight shining through the throttle body blades. I can tell you when you turn out the lights in the garage, it gets dark real quick!!!
But the results are in and correct. When shinning the light through each secondary blade, there is no light what-so-ever coming through. When holding the light up to the primary blade from the back, you can see a good amount of light and also see how far the blade is open. I would venture to say that is my idle problem, no doubt.
Thanks George for the tip and btw, your PM box was fill as of early this AM.
Here are the pics....
light through the primary blade...

light turned off...see what I mean about it being dark.....

flashlight back on....


Now I have to decide and figure out the correct way to accomplish the task. I am not touching the secondary blades, except for a light clean up...hmmmm
maybe not!!!
Have to determine if both the min air adjustment procedure from Dominic and the application of the dry lube will correct the problem. Or just try to adjust the idle stop screw as it is in its present state, and also add the dry lube to help seal the perimeter of the primary blade.

Also looks like I need to sand the TB as some of the finish has cracked off and the top is bubbled, so it needs a refinish. Just might attempt to do it all in the engine compartment and not remove the throttle cable at all.




Yes, for sure....that is where the first batch came from....

Roadster - I just purchased a '90 ZR-1 and would like t learn more about the light test by George; can you please share the link? Appreciate your help!

Congrats again on your purchase and welcome....
There isn't really any link for the test, George told me of a procedure using a flashlight to help determine if your primary and secondary blades are fully closed. All I did was turn out the lights, so that you have complete darkness and shine the flashlight through the front and back of each blade. Now as I have found out, this is more of a test for the secondary blades as opposed to the primary blade. Reason being as was mentioned to me, is that the primary blade does not close completely, so there will be light that does shine through on that blade.
Dominic has a procedure to check out the primary blade by using a thin piece of paper and see how much resistance you have pulling it through the bottom of the primary blade when in the closed position. It should pull through with resistance.
Just to be clear, at this point I am not sure or exactly know what is the cause of my idle issue. I will have to wait until everything is back together and even then I may not know the actual cause because I am making adjustments and checking everything out under the plenum, and the TB. If it still persists after, I would definitely lean towards the TB.
Hope this helps.....
