On my 91 Corolla, my problem (my check engine light was on showing Code 22) was my coolant temperature sensor. My car would die a few times right after starting it the first time of the day, and for the first few minutes, would try to die if I pressed on the gas. I checked (fixed) the touching wires for the plug, and replaced the Coolant Temperature Sensor ($25 at Auto Zone) and it runs like a dream now. The wires to that plug were exposed right at the plug and touching, so I seperated them gently with a small flat head screw driver, and coated them with Liquid Electrical tape (found at home depot) Make sure to unplug the battery first, as even though there's not much going through those two wires, they will bite ya.
