Acura Integra Stalls If I Don't Warm It Up

I have an Acura Integra 1997 RS (Non-Vtec) Manual transmission with 120,000 miles on it. When I start the car and try to drive away it will stall within a few blocks if I brake or make a turn. Then, I have to turn the ignition for about 10 seconds to get it to start again. I changed the spark plugs, distributor cap and did an oil change. What could be the problem? It runs fine if I let the car warm up for 5 minutes.
