HI,
I have a 04 Malibu with 71,000 miles. Everything works except sometimes when you are driving the car and come to a red light, stop sign etc. the car idles real low and it dies. The car will start back up but you never know when the car is going to die. Have had the car at a chevy dealer for 1 week and they can not find out why it is dying. They say there are no codes showing anything is wrong. They have replaced the cam sensor and cleaned the throttle body but it is still dying. Any ideas or has this happened to anyone else? It is the 2.2 echo tech 4 cylinder engine in it.

The key is "sometimes" and "no codes." There isn't much for them to go on. Unless you have the wherewithal to troubleshoot it yourself, I suggest just keep driving it until the problem can be reliably reproduced or get rid of the vehicle.
