9:57: that is the EGR Solenoid that the ECU actuates to send vacuum to the BPT and on to the EGR. It receives its supply vacuum ftom that hose you pointed to on the passenger side of the throttle body.
To get the screws out. I tried to break them free all it did was round it out. BUT i figured out a way number 2 Phelps bit on a angle holder on a drill that hammers when you put pressure on it. It doesn’t take much. It will break free and back right out.
Man, my computer told me it was the throttle control if you do order that part make sure you get an Hitachi I tried one from advanced auto substitute for Itachi worked a little better than the other two that came from car parts but actually come to find out. It was the idle control valve. And yeah, they’re going to rip for a new one. Going to try what you did before I go and buy a new one. But to track down that problem really was a misleading chore, but I got it yesterday temporarily I just reset my throttle control sensor a little higher and the fault light went off then lowered the idle again and the light came back on so I just put it higher, but it still gives a little problem but it’s better than it was temporarily paid 1500 for it but it’s a good vehicle and I like it. It’s a fixer-upper I’m retired and enjoying it. But I did think it had a carburetor when I bought it not a throttle body and injectors. And Freaking sensors. Would’ve been happier with the carburetor and a motor and an air conditioner 😝😝🍻 but it’s been a new learn 😎 you have a good one and I appreciate the video
11:05: it will need to get cleaner than that. When it is fully clean, you will be able to see the smaller diameter section of the shaft that when depressed against the spring will allow more combimustion air into the throttle body. I found i had to soak it overnight in gumout in order to get it clean. Still didn't solve my idle problem, so I'm replacing the MAF next (showed only .015 volts at idle). .

Ok so I'm stuck with a problem that baffles me , starting it cold it runs proper but after it gets warm the idol fluctuates up and down constantly
Hi. My 1994 d21 idle rough but won't die and no power.
It looks like you need a new throttle body all together honestly in the video it looks cracked if so that is a problem..
