1985 Iroc, air leak 5.0, dont know name of the part
TLDR at the bottom
Finally got it to a mechanic, he found air leaks in the egr and a seal and got it running.
Noticed it had a high Idle, and the transmission was jerky, and after drivng it for a few hours it got worse, so the tires spin when putting it into drive.
Had my cousin take a look at it, and he sprayed brake parts cleaner here (second picture), we heard a hiss like if air was getting in (makes sense) and then we smelled the cleaner burn.
What is this part that the screw is holding in? is there a seal and where do I buy it?
TLDR: Mechanic fixed some air leaks, it drove fine but it had a high idle and a jerk when putting it into drive/reverse that would make the tires spin. Found the air leak is at this bolt od the metal it is holding in, What is this part/seal called?

1985 to 1988 Tuned Port Injection engine have a 9th fuel injector called a Cold Start Injector. That is what the bolt is holding in. It has an O-ring to seal it. There is a fuel rail rebuild kit that has all the O-rings in it to rebuild the fuel rail and it includes the O-ring for the cold start injector.

There is a lot more stuff you are going to need in the way of gaskets, seals and other things because you are going to have to take a bunch of stuff off to get to it and all this other stuff needs to be done anyways and it's a case of "While I'm in Here". It's not super easy to disassemble the TPI system and put it all back together properly and it is time consuming to do properly.
Pay one time, cry one time and do it right the first time. Or pay many times, cry many times as you have to go back and do all the things you should have done while you were in there to begin with.

Ok thank you for the links. Do you know if there is another post that lists the other gaskets/seals/ect that I would need? I will also make another post
