Engine code P0170 and P0174 System Lean Banks 1 & 2

Make sure there are no leaks around the intake. Also, check fuel pump pressure to make sure it is within the manufacturer's specs. Finally, check O2 sensors to make sure they are working properly.

Fuel Pump is new and ive check all of the air intake, Also looks like both Upstream 02 Sensors are new but the down stream looks old. Is there only one downstream 02 sensor??? Or is there 2. I only seen one when I was under there.

Thanks for your input I really appreciate your time

I believe there is only one down stream. Even though the upper ones look new, you should check them.

do you have access to a scan tool that has live data? if so, check the short term fuel trims.... do this with engine running.... spray carb cleaner around your intake, etc and see if the voltages change on the fuel trims.... also, drive this with the scanner hooked up, and check your calculated load reading.... when you have the gas pedal floored, such as pulling a hill, or passing a car, your calculated load should read above 90% of not, replace the MAF....

Don't have a scan tool. I unplugged the MAF while engine was running and vehicle died. I'm not sure what that means but the voltage on the sensor looked ok.
