I have an 89 RS Camaro 5.0, I believe its TBI but I'm not 100% sure. Car runs great but whenever I'm at a light or idling the car stalls. It always turns right back on but the problem has become frustrating. I need help with a diagnosis so I can fix it.

 

When was the last time you gave it a full tune up?

 

i purchased the car a month ago, when i took it for a tune up, the people at the shop said it had already been done recently, so all they did was change the oil, add a new fuel filter, and service the fuel injection
