Could be tuneup items, or more likely idle air control valve is dirty.
SOURCE: voltage intermittent, engine missing at all speeds, affect auto trans. shifting, kills hot or cold
The charging system, pedal, and sensors have been checked. The trans. problem and missing problems were the original problems and when my mechanic finally sent me to Chev. none of the problems " choose to show themselves." I should know on Mon. if my mechanic has solved the problems with the greater number of symptoms. Keep me in your files. More later- Bill

Three speed automatic? If so the TCC solenoid is bad.in the transmission. Its under the side cover on the driver side. You can unplug wire connector going to front of transmission so you can drive it until you get it fixed. It will use more gas due to no torque converter lock up.

You need to replace your IAC (idle air control valve). The IAC, like it sounds, control the idle of your car. When they go bad they will cause the low idle and stalling. The IAC is located on the throttle body and is usually held on with a couple of screws. It is an easy relatively cheap fix that you can take care of by yourself. Let me know if you have any more questions. Thanks for rating my response and for using FixYa!

Check the Idle Air Ctrl (IAC) motor. It should allow air to bypass the throttle plate when starting and at idle. if it is not working it could cause veh. to stall.

electrical is the weakest link-you may have a computer with issues and before replacin a reprogram should be considered--what did vehicle scan tell you? Data recorders are often placed in cars that show no codes--Older cars can have solenoids and components that heat up and stop engine--if theres a distributer cap-inspec for corrosion
