86 pickup 4x4 not idling once warm... help diagnose
Hello! I recently bought a 1986 Toyota 4x4 22r pickup truck. Basically I need any help I can get diagnosing the problem. Right now I can start up my truck and it will idle while it's cold, but not once it's warm. The other day it sat in neutral and idled for 20 minutes and when I went to turn the engine off it made a strange dying sound and I go to restart it and it wouldn't idle at all without my foot on the gas.
This all started about a week ago after driving a pretty bad 4x4 road down to the river and hitting a few bumps pretty hard. On the way back up the road I noticed the dash lights coming on when my speed got real slow during the gnarly parts of the road. By the time I got back to the main roads my car wouldn't idle at all. If i sat in neutral it would die, with the clutch in it would die also, unless I pressed the gas. Even if I was moving at 30 mph or whatever speed and stuck in the clutch for more than a second, the car would die and lights would come on, steering wheel would lock.
The other day I took off the Carburetor pan to check hoses and actually saw one hose that was disconnected, I reconnected it and it actually started up and idled, when it wouldn't just before reconnecting the hose. But then I reverse, stick in the clutch and it dies again. I think that fixing that hose helped a little but didn't solve the problem.
Someone recommended that I replace all the hoses under my hood because they're old anyway, somebody else told me it sounds like a sensor problem. What do you guys think? Any help is greatly appreciated. Thanks.

Update: I just turned my truck and it was idling fine. Then after about 10 or 15 minutes the idled changed, I heard the difference, but it was still running. Then after about 5 minutes I hopped in and gave it some gas. After doing that, the truck would no longer idle, dying within a second of letting foot off of gas.

Update: while truck was running and warm I opened the air cleaner house and manually adjusted the passenger side carb, It was completely vertical and I flattened it out a little)as far as it would go) Once doing this, The truck would idle once again, but then after gassing it again, the problem would return. The valve(s) must be broken in the Carburetor, time to rebuild it I suppose.
