TB removal and then some!!!
Thanks for sharing all these details and nice photos Tom! I have been having some idle issues since I got this 95, but time to address it. I have this NIB TB and might as well put it to use instead of on the shelf for the last 14 years or so.
 I'll add the Carter Bling Special while I'm at it and get the stainless fastener kit from Jerry. Thanks Phil for the adjustment screw tip and I'll do that while I'm at it. I'm waiting on my ported plenum and IHs from Corey so I can do this all at once. I would be better off sending the old TB to Marc to work his magic, but can't afford the down time right now without a garage. I have to do the coolant bypass too. Best wishes to get your issue squared away. Sent from my iPhone using ZR-1 Net Registry

Re: TB removal and then some!!!
Marc offers a very simple coolant bypass solution utilizing a bent aluminum fuel line that passes under the plenum and connects the throttle body coolant hoses to each other.
The solution I have seals the coolant passages at the injector housing (both sides) and includes a small valve to bleed the coolant system. |

 Philly Cheesesteaks & Hoagies and $$$.....lol just had to try!!!Just going to take my time and get this idle issue fixed. A learning experience for sure. Also will wait and see what the results are with mine before thinking about sending the TB out to Marc for a check-up. Glad you enjoy the pics, I enjoy taking them!!!  Keep us posted on your progress too... Quote:
I guess my concerns are winter driving, (which I don't use the Z that much), so not a concern....lol The other one is air being trapped in the system....and I assume your bleeder valve would solve that problem. I know there are a lot of members to have done the bypass in different ways, so it is something to be considered.

Thanks for your thoughts. I can't even get myself to break the seal on the packaging to know I really want to use it let alone sell it. Those cheesesteaks and hoagies sound tempting though.... You are approaching it the right way to take your time and do it right. I'm gong to do the same to confirm what the real issue is, but earlier discussions with Marc point to TB issues. If I could put my car down for a few weeks I rather send the TB to Marc if so, but my situation here poses some challenges for down time with the Z. You're almost as thorough as Dynomite Cliff and you're going to help folks out with all the details and photos. Will post up when I get to my projects and just collecting up all the parts now while waiting on extra top end components. Thanks for sharing.

No problem...lol Yes, they do sound tempting....and we just found another place that has the best cheesesteaks to date in our area. If I could figure out a way to get those cheesesteaks and hoagies out to you and still be fresh, it would be my treat. hmmmm, have to work on that!!! I know what you mean about breaking the seal, years ago I found and purchased an NOS Q-Jet for a 70 Corvette 454 motor still wrapped up in the original box . And it still is today.....lol Intended to use on my 74, but ended up getting my original rebuilt, which I will end up using. I'm glad you used the words "almost as", don't think I could ever match Cliff!!! I do hope the details and photos help the individuals as mentioned before, to take on a project that maybe they thought was beyond their capabilities. When all back together, if I end up having the same issue, then I will assume it could be the TB. But until then, and as suggested by other members, that isn't the issue. We shall see.... Anxious to hear your progress when you can troubleshoot your issue. Keep us posted for sure....

Re: TB removal and then some!!!
FYI...This is the extended Torx set I found which also includes the T-40 needed for the plenum bolts. Although this may be common knowledge among the seasoned members, I would suggest a purchase of this kit or a similar one for those members thinking about doing their first plenum pull. The extended T-40 will not only fit in those two tight spaces mentioned before, with ease. But you will now be fully seated in the bolt during disassembly and when putting the correct torque on these during reassembly. And not have the fear of stripping out the head of the bolt.

Re: TB removal and then some!!!
Just want to say I can't comment enough about all of the contacts from PM's, phone calls, texting and posting that I have been receiving lately with thoughts, ideas, and suggestions concerning the idle issue.
Again, it is very much appreciated from all and as I always say, a good continuing learning process along the way....Thank you all!!!  Been talking to VetteVet (Jep) on numerous occasions and he also came up with an idea for replacing that connector. And that is to find 2 90* elbows that would fit onto the solenoid and also be large enough for the 2 lines to be inserted into them. And then use a small plastic tie to secure. Yun has also has suggested to Epoxy the lines into the connector. Also I determined that what Yun used during the "first" plenum pull IIRC was a piece of "sticky" tape around the outside of the line and then inserted into the connector seemed to work. As you will see in the pic, once I reinserted the line in question, it was in there snug. I now don't think that there was even a slight chance that the line ever popped out on its own. It most likely came out when I pulled up on the plenum during removal. So whatever Yun did before apparently worked. It also looks like there was a plenum removal along the way before my ownership, as this connector has a plastic tie. And from what I have been told, is that the factory did not use plastic ties. the connector...it was not as soft as what I thought last night...the opening is soft, but the connector itself is firm and doesn't have any cracks...the one opening appears to be slightly elongated...  after reinserting the line in question.....a very snug fit as per Yun...

Thanks for your thoughts and offer. The closest I have eaten lately is Subway steak and cheese sandwich. Not even close. I figured that new TB does no good sitting on the shelf and this is my last hurrah with this car as I'll probably get rid of later and move on. Yes, Cliff is a legend already with all of his posts and thousands of hours into tech threads. Thanks and I'll keep up the great posts. Sent from my iPhone using ZR-1 Net Registry

Yes Subway is ok, but no substitute for the real thing.... So your going to use the NOS TB and eventually sell the Z??? I agree with you on Cliff, great research and tech threads as I'm sure everyone would agree... Always enjoy your contributions.... Sent you a PM.....
