You own a high end luxury vehicle as do I, 2005 ES330, the dealership is the best place to get Lexus problems fixed. With my own vehicle, I had a thermostat fault code come up, and like you it would reset itself and come back. The code said it was the thermostat and I queried it with my tyre guy. He also said it is a thermostat code. I said but it isn't overheating. He told me that the computers in Lexus are so clever they are actually looking for the water to reach x degrees in x minutes. He replaced the thermostat, the fault never came back. Anyway back to your P0172 Error code.

Possible causes
Faulty front heated oxygen sensor
Ignition misfiring
Faulty fuel injectors
Exhaust gas leaks
Incorrect fuel pressure
Faulty Mass Air Flow (MAF) sensor

The first thing I would try is that stuff that you add to your fuel to clean the injectors.

P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks.Replace MAf sensor,if cleaning the MAF does not help.
OBD II P0172 Fuel System Too Rich (Bank 1).P0172 - System Too Rich (Bank 1) Essentially this DTC means that an oxygen sensor in bank 1 detected a rich condition.
When the code says that the Fuel System is "too rich," it means that the computer has been subtracting more and more fuel, which is called Long Term Fuel Trim. Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent. When a code P0172 is set, it means that the Fuel Trim is anywhere from -15 percent to as low as -30 percent compensated. When this happens, the computer knows that there is an improper condition in the control of the Fuel System.


Thanks.
