Default wont stay started

hey just got my car out of storage on tuesday (87 n/a 5 speed) she ran and drove fine untill about saturday night. saturay night she would start but than would die shortly after unless i held my foot on the gas. than today i went to work and even with the pedal to the floor she wouldnt do anything for a few seconds than shed finally slowly rev. had to leave my car at work today didnt want to get stranded. me and our maintence guy wen through all the vacuum hoses and everything seems to be ok unplugged plug wires one at a time but everytime he unplugged one it made no difference which worries me too. Plus i did the diagnostics and code 22 flashed (temp sensor??) any one experience any of these problems or might know what it could be thanks.

Default Coolant temp sensor

Your ECU is telling the truth. My 87 N/A car had the same problem, poor running, code 22. I reseated the plug on the coolant temp sensor (two pin plug on thermostat housing next to the timing belt cover) and it worked for awhile. My ECU harness is basically brittle from running in a desert environment for over 10 years so I had to splice in two new wires and the problem was solved. The temp sensor is probably OK, it should read between 200-400 ohms when its warmed up.

Default temp guage

The temp gauge sender is a different sensor located on the right side down a few inches and is a single terminal.

Default charcoal cannister?

Check all your connections to the charcoal cannister. Its supposed to burn the vapors that evaporate from the gas tank. If a hose came off then it could be the fumes from the tank venting in the atmosphere and entering the inside of the car. That is if there aren't any visible fuel leaks anywhere.
