I need to know what this is.

this broke off my manifold but i can't find it in my Haynes to order a new one. Also i need to know how to take the big a$$ bolt off the manifold to get the new one back on.

Thank you

Looks like a BVSV... Or basically a temperature activated vacuum switch.

tricky thing is the one that is for sale for the 87 model is not the same one. The one that is suggested for my motor is the cj model or the one for the 80 to 86 amc motor. Should I stick with the amc one ?

stick with the one for your vehicle. They have different temperatures that activate them.

Has nothing to do with the Nutter or aftermarket carb.

It is to run the EGR valve and gas vapor canister which aren't computer controlled. You can run without the canister if you (and the state where you live) don't care about puking gas vapor into the air and it will just run a little dirtier and a little hotter without the EGR.

it will run if you by pass it but when cold it will run rough. the cto allows the engine to warm up before opening the egr and carbon can.

that would make since why it has been running ruff and dying out so much when she has been cold, **** is killing me trying to get it off. I have one on my parts jeep and it is also the five hole version so i am not going to go with the three hole model that they are saying is the right one for my jeep.
