Question about 1992 Buick Skylark
When the motor is idling the ESC (electronic spark control) module (also called ignition module) is responsible for the spark timing until the engine speed rises above 1500rpm when the PCM takes over. There is also a sensor behind the crankshaft pulley which sends a switching signal to the PCM & the ESC. Both of these are possible culprits. I suggest try an ESC (mounted underneath the three coils on left-hand side of the motor, and remmovable by removing the 6x7mm bolts holding down each of the coils and an 8mm bolt holding the electrical connector in ) from a junkyard from a know working car, if this does not solve your problem the crankshaft sensor is the next stop, To remove this you need to jack up the passenger side of the car and remove the front wheel, then remove the plastic cowling (being careful to unclip the cables from the cowling) using the 4x 7mm bolts at the top and side. When the pulley is in view remove the 24mm bolt holding the pulley on and the switch is behind it mounted on two 10mm bolts . good luck

You have probably solved this problem by now, but this may help others. It sounds like the TCC Solenoid. (Torque Converter Clutch Solenoid) Instead of overdrive, the 1992 Skylark has a torque converter clutch designed to save fuel and run cooler for highway driving. My understanding is that there is fluid and a float valve, so when it heats up it can get stuck in a higher gear until it cools down. As soon as you get above about 40-45 mph, it will stick and then you stall when you return to a lower speed. It will then be fine after it cools for a few minutes and repeat.
I have a 1992 Skylark and was able to unplug it with little repercussion. You can stop in NAPA or any car parts store and ask them to point it out to you, then simply unplug it. It can be replaced, but it's a few hundred dollars because they have to go in through the driver's side wheel well to replace it. Unfortunately for us, that's probably half the value of our car! The only thing that happens is that your check engine light will come on frequently because it senses that it's unplugged. Also, I've read that your car's engine will run a little warmer and you will get less gas mileage on the highway. It really hasn't been noticeable to me though and I haven't had any problems since I unplugged it well over a year ago.

Turn on your heater to see if it works it sounds like your thermostat might be sticking.
