P0172 Code Fix: Fuel System Too Rich Bank 1 - 2003 Chevrolet Cavalier 2.2L OHV

I'm experiencing a P0172 diagnostic trouble code on my 2003 Chevrolet Cavalier with the 2.2L OHV engine. After researching, I removed the air inlet duct and found it was clogged with fuel. Additionally, I noticed a cracked grommet in the hose connecting the fuel pressure regulator to the resonator body—this appears to be leaking fuel. The fuel leak is likely causing the system to run too rich. Here are my scanner readings: - Fuel System 1 Status: CL - Fuel System 2 Status: -- - Calculated Load Value: 28.6% - Engine Coolant Temperature: 118°F - Short Term Fuel Trim Bank 1: -7.0% - Long Term Fuel Trim Bank 1: -7.8% - Intake Manifold Absolute Pressure: 9.9 inHg - Engine RPM: 914 rpm - Vehicle Speed: 0 mph - Ignition Timing Advance (Cylinder 1): 8.5° - Intake Air Temperature: 69°F - Absolute Throttle Position: 0.0% - Oxygen Sensor Output Voltage (Bank 1, Sensor 1): 0.825 V - Short Term Fuel Trim (Bank 1, Sensor 1): -6.3% - Oxygen Sensor Output Voltage (Bank 1, Sensor 2): 0.625 V - Short Term Fuel Trim (Bank 1, Sensor 2): 99.2% The negative fuel trims suggest the engine is running lean, but the presence of fuel in the intake suggests a rich condition—this inconsistency points to a leak or faulty component. I suspect the fuel pressure regulator is malfunctioning due to the cracked grommet and visible fuel leakage. I'm seeking advice on whether this could be the root cause and what steps to take next.
