Can you drive your car if it stalls when idle?

I had that issue with my 02 cougar xr. It started and drove fine but at stop signs or stop lights it would die. There are a couple of ways to fix this. I replaced my IAC valve or idle air control valve and it idled better but after a while it would still stall in the long run, so there's a possibility. Before replacing it take it off and check for cracks and gunk build up. The next step is i checked for any leaks in vacuum hoses. The problem i was having was that my TPS (throttle positioning sensor) had fallen out of my intake system. I hope this helps.
