It Sounds like misfiring and it shakes the car in synch with the idle. You cant really see it that much but the hood does indeed move a good amount. Shakes you in your seat.

On post 24. That line that is melted is supposed to be the a vacuum line with 2 one way check valves that go from the vented optispark to intake manifold. It will need replacing as well.
Thinking about getting the petris vaccum lines set.

The set also comes with the mass airflow duct to optispark.
Jaime, Don't throw away the two valves. Actually, one is a one-way check valve (the smaller one), and the other is a filter/orifice unit. It allows the hose to pull a very slow, metered flow of air through the Optispark to keep moisture and (corrosive) ozone fumes out of it. They just started reproducing these. For a long time, you couldn't get the orifice. You could probably just put new vacuum hose on them and reuse them instead of spending $60 - $80 on a new set. If nothing else, I imagine someone here would take them off your hands...
I was thinking about that as well. I was also thinking about using fuel hose and protection from wire loom instead since it is thicker and better material.
If I cant use fuel hose then vacuum hose will do.

Just made my own hose... only cost me 10 bucks! So I saved about $55. Had to order a 3/16 to 5/16 heater hose connector for the optispark to filter/orifice. The rest was just 3/16.
The long 2 foot hose that goes from MAF duct to Optispark was also 3/16.
Sorry if I missed it, but what thermostat are you putting in? I just inherited my Father’s 95, 46,000 miles running awesome. Changed all the belts, fluids, filters, plugs tires etc. But one thing I noticed my dad did (probably 20 years ago) was put in a 160 degree thermostat. It was an Arizona car, (garaged and soon coming with me home to California) so I can understand him wanting a cooler T-stat, (isn’t 185 standard?) but I am wondering if when I get it home I should change it out(?).
180 is stock yes. Mine currently has an autozone 160 stat for the past couple years. Honestly it doesnt make a difference, once they reach operating temperatures they will all always just be open. Thermostat doesnt make the car run cooler. They just open at set temp say 160°F to let coolant run through the radiator sooner (160) rather then later (180). Regardless the motor will reach operating temperature anyway.

Sorry guys for not posting, my brother has a bunch of parts for the 95 vette and he wants to do it all in one go. So once he has everything ready I will post our progress. It will be a very nice car when complete.
I'm sure when you guys see it you guys will love it and appreciate the revival of this old vette.
I am the 6th owner of the vette (gave it to my brother so I guess he is the 7th owner)... The car was even leased and it has seen better days. I'm glad my brother and I are saving this c4 from c4 certain death.

It sounds like you guys are progressing nicely. Looking at a 95 conv. this weekend with some issues. When you're all done please, please remove the ZR1 badge off of the rear bumper. You don't want to be labeled a poser. Keep up the good work.
We got ourselves the Jegs Optispark. We put thread sealant on the 4 bolts that hold everything together so no such water can go in from there. We also put silicone around the two caps so nothing can go through either.
