Just pulled this code on the scanner, can't seem to find it anywhere. Any suggestions

P0170 is Fuel Trim Malfuction (Bank 1)

Check the following:

• Volume air flow sensor output frequency
• Injectors
• Fuel Pressure
• Intake air leaks
• Engine coolant temperature sensor
• Intake air temperature sensor
• Baromentric pressure sensor
• O2 sensor
• Exhaust manifold cracks

I just had this CEL recently and the problem was my front o2 sensor.

Yup, I had the same cel a while ago. It was the front o2 sensor like stated above.

I have code P0170 that sends the check engine light sometimes and then the check engine light goes off on its own too. What my car is doing is on wide open throttle it doesn't make it much higher then 4000RPM would a front O2 cause this and if so why woun't I have an O2 code?
