Lean codes bank 1 and 2

Hello, I'm Danny.

Yes, that is entirely possible. Is your check engine light on or are you getting that code? What is the actual year of your car?

Please run down this guide and report back.

A Continental with a 4.6, fuel pump is the prime suspect and fuel pressure should be verified. Let us know the actual year and we can get you the specs and instructions.

Car listed above is a 2001. It has a new fuel pump and fuel filter. it runs great it set the codes bank 1 and 2 lean codes, fuel pressure is 50lbs there are times that it stalls out and times that you push on the gas and nothing and lately it has shut off at a light. the light comes on when at a cruse about 60 mph, still running great. Intake manifold gasket been replaced.

If your scan tool has access to sensor reading, the baro pid should read 155-158hz at sea level, short term fuel trims and long term fuel trims should be within 5% of 0. A high ethanol content in the fuel can cause this concern also, that's assuming that this is a new concern.

Hello again.

Did you say the check engine light comes on at traffic lights? That means a diagnostic code is stored. If you don't have access to a scanner or code reader most auto parts stores have a tool loaner program and will rent you one. Here is a tutorial showing how to check codes:

After retrieving any codes get back to us with the code information and number and then we can properly diagnose the symptom. Hope this helps and thanks again for using 2CarPros.
