Rough idle, hard to start when warm?

Hi,

My van is idling rough when warm. When cold everything's fine, after 2 or 4 minutes idle starts to be rough.

When I try to start the engine when it is warm, i need to press on gas pedal to get it start after longer than normal crank time

On some occasions, I noticed that engine hesitates when I command acceleration.

Went I bought a ODB2 scanner, it gave me those codes

P1131 sensor indicates lean
P1150 fuel at trim limit
P1151 sensor indicates lean
P0171 system too lean

Scanner is not able to self-test oxygen sensor-test incomplete

Thanks for your help.
