I've got an 86 4Runner, 22re, off the line in May. I am getting ready to delete the EGR system to clean up the vac lines. I am reading that some early 22re's don't have an egr temp sensor. If it does, where will it be located? I ask because I want to ensure I am not just missing it. If I have one I want to have some 10k ohm resistors on hand, but with no radio shacks anymore, it's proving a chore to find some locally.
Also, does anyone know the size of the hole for the metal EGR vac lines that screw into the top of the Cold Start Injector sensor? I want to pull those lines and cap it off. I want to have all parts on hand before I start tearing it down.
...Also, Will cleaning those sensors up to be shiny again be as good as replacing them? I have a dremel with a polishing wheel.... Ideas.
Absolutely! those sensors should be cleaned at least once every 30 years
The thread for CSI timer switch mounting is often overlooked. It should be cleaned to bare metal and they should have god electrical contact because that's where the timer switch gets its ground.. https://cimg0.ibsrv.net/gimg/www.yot...b5b25edb96.jpg
Hahaha I'm 2 years over due then. I have changed the ECT out a while ago with a duralast one. But I kept the old original. Maybe I'll clean it up and put it back in.
Any tips on keeping the cleaned grime on the OUTSIDE of the sensor hole and not the inside, or does it matter?

Rule should be rephrased... "...should be cleaned at least once every X years, where X is current year minus year your truck was made - LOL!"
Ideally you'd want to keep the dirt out, right before a flush, but it's minor scaling; should not hurt.
That's awesome. I'm finally taking the time to learn to read electrical diagrams. I built a custom car computer from the ground up using a raspberry pi, so while I was soldering a micro amp I began also learning diagrams. Once the basics are grasped they aren't nearly as intimidating as initial preconceptions.
Nice!
I have an opposite idea in mind... build something very simple that can replace the ECU and keep the truck running in worst-case scenario.
I would be absolutely interested in that. Please do it.
The car puter I built was for a replacement head unit. I wanted Bluetooth streaming. I needed to replace my stereo, so I decided to go the custom route with a fancy touchscreen. It also tethers to my phone, so while I'm waiting for the girlfriend I can watch toyota youtube videos on the 7inch touch.
Oh and since it's brain is a raspberry pi I can swap out the card and play some Nintendo roms when I'm truly bored in the parking lot.
