1981 Toyota pickup sr5 22R rough idle miss fuel cut out idle cut solenoid fix emissions computer

I was able to find the issue thanks to this forum post. https://www.pirate4x4.com/threads/22r... I also pulled this from another forum which I can't find anymore. "I recently fixed my idle problem on an 83 carbureted 22r using some of the info found on these pages. I had the same problem where it started OK, ran a high idle, came down to a normal idle for 5 minutes, then died. Carefully look down the throat of the carb. You should NOT see any gas dribbling into the engine if its idling properly. My fuel cut solenoid was not engaging. It should click when the key is turned on. I removed the solenoid and put the two wires across the battery, it then clicked. One side of the mating connector for the solenoid has +12 v. The other side should nearly go to ground when the key is turned on. Its not a direct short to ground because it goes through some electronics. I traced the control wires back to a gray box on the driver's side kick panel The box said "emission control" and had one large green connector. I traced here by measuring continuity from the connector under the hood to the green connector on this gray box. I removed the 2 screws holding the box together, removed the circuit board inside and started to trace the circuit on the board when I noticed "cold" solder joints on most of the green connector pins on the circuit board. If you look at them with a magnifying glass you can see the cracked solder around the pin. I re-soldered all the pins of this connector on the circuit card and now it works great. Controls the solenoid nicely now. These cold solder joints happen due to the years of temperature cycling. Hot summers & cold winters. Most of the pins had bad joints, so I probably fixed other problems I didn't even know I had. 2nd Truck: My son also has a similar truck, 1986 carbureted 22r that wouldn't idle well. After my experience I had an idea what to look for. His problem was a stuck solenoid. We removed it and did the same as above, only it didn't "click". Cleaned it with carb cleaner, tapped it lightly, and put the controls across the battery. It eventually broke free and now works. His idle problem has been fixed too. Hope this helps someone." Good luck to all who are having this issue.
