Yesterday I stopped for fuel and when I started the car to leave after fueling it hesitated and then ran fine for a few miles and then stared missing and after a few more miles it quit nrunning and I pulled over and let it cool off then it stared again and I drove a few more miles and stared missing and I pulled over it didn't die, it would idle but would not gain enough power to drive Im shut it off and let it cool about 1/2 hour and then drove a few more mile and same thing again I had similar problem last week and changed fuel filter it ran fine until this.

Welcome to the forum, thanks for the donation. I'd use a gage and check fuel pressure, 55--62psi, gasoline v8. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. Test when the problem occurs.

Hi, the PO codes, fuel trim lean. P1 codes says 02 sensor/s not switching from rich to lean properly. My first thought is an injector leak. Use a gage and check fuel pressure. Check that the pressure holds, when everything is turned off. Another possibility is 02 sensor or wiring circuit problems.
