I own a 86 Fiero and I did a tune up, fluid change, etc etc. It was running yesterday (but would stall in gear). Today I can't get it to start up and stay running.
#Pontiac Fiero v6 ('86) Starting Trouble

I have an 86 Fiero SE. I recently changed plugs, cables, distributor, cap, flushed coolant, changed oil, new filters. The car has been sitting essentially since the late 90s. Now, I finally got it to run (yay!) but only in idle, and the idle is high. (2000-2500 [3000 if pretty cold]) The issue I'm having now though, is despite the clean (albeit high idle) when I shift into gear, I get a very rough transition at around 500-1k rpm and then the car sputters and dies as soon as even a drop of gas is given. This happens in drive gears and in reverse. But I can idle indefinitely and even apply throttle while idle without any noticeable issues.
Current engine code is a 15 so I'm planning on replacing the temp sensor and thermostat here in a couple days, but I don't think that would cause this issue because the temp sensor has a fallback, doesn't it?
Looking for any help,

P.S. my timing is several degrees ccw because otherwise the car will slowly die in idle. Going based off the harmonic balancer, I have an idle of 1.5k rpm for 30 or so seconds before it slowly dies off. There's also pretty bad throttle lag if I stay at the timing from the harmonic balancer. Even though it has the best idle rpm.
So I took a look today, (I'm still getting used to the mess the old owner made) and here's what I found:
The egr tube is missing (I knew that) but I have it blocked off with a plate, and the vac line is blocked too. Theres probably an exhaust leak bc of that but surely not a vac leak right?
The connector for the TCC is just gone. So its already unplugged I guess.
The fluid levels are all good. There's no thermostat in (I ordered one already)
I think that's about all I found so far. Despite cranking up all day yesterday with no issues, I can't seem to get it to really run. To be fair, I don't have a working gas gauge so I can't tell when it's out or not. But I put a gallon in yesterday and haven't been driving it so I doubt it's out?
