Some things to try.........unplug your MAF sensor and see if the car runs any better. If it does than the sensor took a dive. Read this to..https://www.gmforum.com/t278926/
M*** Air Flow sensor
A bad IAC valve will also snuff out a motor when idling. Try tapping on top of the IAC to see if things improve or take a hair dryer and warm up the sensor to trouble shoot it.
