I have a 99 Saturn SL2 with over 300,000 miles on it the car's been very good to me until lately. As I'm driving the car I have an intermittent power loss it seems as if it's a fuel related problem. I have already replaced the fuel pump, the fuel pump relay and the fuel filter. I don't have any codes or a check engine light on. If anyone has any ideas please let me know. Thank you
