Q: my 2003 chevy impala stalls out in traffic on 2003 Chevrolet Impala

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The car starts and seems to operate early in the day and on highways. It stalls out in traffic. We've had numerous so called "mechanics" who've diagnosed our car and tried, unsuccessfully, to fix it. My wife and I are retired and rely on this vehicle as our main source of transportation. Can you help?

Hello; in traffic you are probably experiencing a lack of consistent fuel pressure, or are not getting enough air -- or are perhaps getting too much air into the engine. Last, you could have an exhaust restriction. A good technician can troubleshoot step by step to find out what is happening when the problem is occurring.
