ECU COde - P0170

Fuel trim malfuction BANK1

Do you guy know what this might mean? I have 102K miles on my 95 MAX

I received that code after this mechanic from Autozone performed the diagnostic service.

My car has a hard time starting and once it completly stopped while driving on the expressway. Is it the fuel injector?

DTC 0115

Diagnostic Trouble Code 0115 indicates a problem with the fuel management system on the right cylinder bank.
The right bank is also called the rear bank. It is cylinders 1,3,5.

The Front Heated Oxygen Sensor for the right bank sent signals to the Engine Control Module indicating an
excessively lean fuel mixture. The ECM attempted to correct this problem by directing the fuel injectors to
supply more gasoline. Further signals from the Oxygen Sensor indicate that the attempt to correct the lean
mixture condition was unsuccessful, and the fuel mixture continues to be too lean.

Possible causes include ...
- Intake air leaks
- Defective Front Heated Oxygen Sensor
- Fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow Sensor
