Okay, 300 is for a misfiring in more than 1 cylinder. The most common reason is the fuel pump. Low fuel pressure will cause this.

1101
Usually the mass air flow sensor
DTC P1101
DESCRIPTION
The purpose of the global air diagnostic is to detect an airflow error. When this diagnostic determines that there is an airflow error, the DTC P1101 sets immediately. When this occurs, the fuel system operates in a default state and the engine control module (ECM) performs a series of tests to determine which of the following sensors or systems is the source of the error:
- DTC P0068 throttle body airflow performance
- DTC P0101 mass air flow (MAF) sensor performance
- DTC P0106 manifold absolute pressure (MAP) sensor performance
This DTC is designed to always set with another DTC as long as the ECM has had enough time to run the series of tests.
DTC DESCRIPTOR
This Diagnostic Procedure supports the following DTC:
DTC P1101 Intake Air Flow System Performance
CONDITIONS FOR RUNNING THE DTC
- DTCs P0121, P1516, and P2108 are not set.
- The engine is running.
- The MAP sensor is less than 99 kPa.
- The engine is in Closed Loop fuel control.
- DTC P1101 runs continuously.
CONDITIONS FOR SETTING THE DTC
If the ECM detects an air flow error, DTC P1101 sets immediately.
ACTION TAKEN WHEN THE DTC SETS
- The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
CONDITIONS FOR CLEARING THE MIL/DTC
- The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
- Clear the MIL and the DTC with a scan tool.
