It isn't Anthem's fault. Everytime it goes in it comes out running good but the problem is that is doesn't stay that way. It is doing it both at start up and after the car is warm. Between gears and on initial starting it hesitates, misfires a bit then acts fine. It is a bit worse at lower RPM's. The EFI system can only be tuned by computer. Before everyone jumps on the bandwagon about how evil EFI remember that if it was so bad why does every car in america run on it? I was just looking for suggestion on what would be making it happen.
