1990 NA Auto - Squeeling/almost stalls
 

Hey guys - just bought a '90 300zx auto and drove it home tonight. Drove about 20 miles and it drove like a champ....until I got into the city. I stopped at a red light and when the light turned green and I pressed the gas, the car almost stalled out (RPM dropped below 1, car shook, squealing) didn't stall out and drove fine after that. Sorry if I missed a post anywhere about this, but any help would be appreciated.
