Two days ago I drove my 91 toyota 4x4 pickup 22re for 45 minutes in the rain, stopped at the job for 1 hour. When I tried to dirve away, the truck started, I made it out of the driveway and couldn't go forward. Back to neutral, idle went from poor to regular. Sat there for twenty minutes attempting to get it running long enough to pull back in the driveway. Tried wd40 and pb blaster on the wires, no help. Could not find wire dryer. Let the truck sit overnight, started it in, the morning, ran fine for longer than a minute, now much dryer, no rain, and ran fine for over that minute, then the idle dropped low til it stalled on its own.
Several things have been done to my truck very recently. New head last fall, timing chain too, just changed the muffeler 2 weeks ago, but could not install my rear o2 sensor because my truck is of course Cali. Emissions, and I am in Ny. No, pipe has the hole made for my truck, the sensor does not fit the piece I can buy and weld to the pipe so that is out. I have not had the time to fabricate the piece with bolts to weld to my pipe, to make a long story short I have had my o2sensor out for this entire period of time, strapped to my frame to stop it from dangling. Just saw in chiltons not to get them wet? Was this a big nono?
I have had a big loss of oil, never before. Almost a quart every tank and a half, and can see no leaks. I just changed my oil and added a bottle of lucas with the oil.
Last of all, when I have been driving to the job in the mornings, the truck sputters like the filter is plugged, but I just changed that with the head. I bogs as I turn the corner, I get down the. Road a half mile and it is fine, but it bogs a little at the start. Yesterday when I tried to start it, it started, but when I gave it gas it bogged down. This seemed to be happening mostly when starting and going for a mile.
This morning I changed my spark plug wires, cap and rotor, checked cyl.2, clean, and started it. It died in under 10 seconds, and won't start now. Ideas?
Any ideas?

I did some tinkering. I opened my gas cap, and unplugged my rear o2 sensor. Now it starts, wants to die on no gas and heavy gas, but just holding my foot on the pedal gentle it runs. Push further, it dies

Have the fuel pressure checked.
Check the Throttle position sensor.
Check for trouble codes.

Have not been back to the truck, much work. I am fixing my o2 sensor before I check the codes ( thank you for the advice thus far ), and I had to buy a bosch lsh 24 sensor to screw into a bung after the cat. Converter. I know very little of wiring. On the new bosch sensor I see 2 white, a grey and a black. The connector on the old sensor that I am splicing has 2 black, a blue and a white. The male connector end off my truck has a white, a red, a white with red, and a red with grey(dark stripe). I looked at the connectors. Blue to a white (connector on sensor to truck), white to red, a black to the white with rex, a black to the red with grey. From the old sensor connector, I want to hook up the two black wires to the new sensors two white wires, the white to the new grey, and the blue to the new black. Am I on the right track?

So I made it back to my truck. Found a wiring diagram that fit my needs,
Installed the oxygen sensor and checked the codes. 3 and 1 is the flash sequence I get. Do I still check the fuel pressure and the throttle position sensor?

31 is the code for MAP or Air Flow depending on the system on your vehicle. These are the items you need to check.
