P0300 Fault Code on 1999 Olds Alero 3.4L V6: What Does It Mean and How to Diagnose?

Model: 99 Olds Alero 3.4L Fault Code: P0300 Posted: 2015-09-14 13:56

I'm trying to understand what the readings mean when I freeze the screen on my OBD2 scanner for a 1999 Oldsmobile Alero with a 3.4L V6 engine. The fault code displayed is P0300 — indicating a random/multiple cylinder misfire detected in the fuel system. Key data points from the scan include: Fuel System 1 (OL), Fuel System 2 (N/A), Load Percentage at 15.7%, Engine Temperature (TP) at 56.1°C, Mass Airflow (mass) at 23.89 g/s, Manifold Absolute Pressure (MAP) at 99 kPa, RPM at 1630, Vehicle Speed Sensor (VSS) reading of 0, and Short Term Fuel Trim 1 and Long Term Fuel Trim 1 both at 0.8%. I'm looking for clarity on what these values indicate and how to troubleshoot the P0300 code effectively in this specific vehicle model.
