Bank 1 & bank 2 sensor engine running to lean

The car runs fine without any stuttering or power problems.

It starts and goes normal from a stop.

Is this an issue?

Should I disconnect the battery and reset the computer?

You have a very minor problem !

* In the vast majority of cases, simply cleaning the Max Air Flow "MAF" sensor does the trick. I find it's best to take it off and spray it with electronics cleaner or brake cleaner.

MAF Sensor Location? Right near your air filter box on a large black air intake lead hose. It is a small black module with "Max Air" printed on it and a direction arrow (Air Flow).

* Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling.
* Inspect all vacuum and PCV hoses, replace if necessary.
* Check for a dirty fuel filter and proper fuel pressure.

Remove your negative battery cable to clear code and re-set. Wait 10 seconds. Connect the battery cable. The CEL (Check Engine Light) will be out and you will be all set.

I "strongly" feel that cleaning the MAF Sensor will solve your problem with code P0174.
Good luck;
