When I drive my car in residential areas I will be at a stop and my car rpms will go up and down and then the car dies. But, if I hit the gas it tries to go so it doesn't die, just stutters in a way. When I accelerate on the highway it just seems like it stalls a little but I don't have major issues, not sure if it is related. I have gotten a new battery, new throttle body (which seemed to help but now is acting back up), throttle body cleaned (again helped for a couple of days and acted back up), new variable valve timing solenoid, new spark plug in line 4. I am dumping so much money in it and no one seems to know what is really wrong with it. Please help.

Me, my 11 and my 6 month old baby was driving down dawson rd, in albany GA , and the air condition started blowing hot air, and the car shut down in traffic. Thank god the cars behind me was at a red light. As soon as I put it in park and the key to off , it cracked right back up. Last year I had this same problem and Prince said that the computer showed nothing. Is it going to take a mother and her two girls getting killed in traffic for chevy to look into the problem, and address it. Because I promise if something happens to my girls because of the malfuction of the car, I will get a lawyer.
