Some customers may comment on a rough running engine with the Malfunction Indicator Lamp on.
Condition
Cause
Upon inspection, a technician may find DTC P0300 set along with a misfire and low compression in one
or more cylinders.
This condition may be caused by a damaged piston requiring replacement.
Correction:
Repair the engine mechanical concern based on the results of the service procedure below.
Service Procedure:
Perform Engine Compression Testing in Service Information.
If low compression is found, perform Cylinder Leakage Testing in Service Information and record the test results to isolate the
concern.
NOTE: (To isolate the source of cylinder leakage to a valve or cylinder sealing issue, it may be necessary to remove the intake and
exhaust manifolds).
If excessive leakage to the crankcase is isolated, check all four cylinder walls for damage.
If the cylinder wall surfaces have not been damaged, replace all four pistons and fill the crankcase with current specification Dexos
oil. (refer to latest version of Corporate Bulletin Number 16-NA-367).
An un-metered air leak in the induction system, or an engine mechanical issue causing rough running, may cause the ECM to learn an
incorrect Throttle Body Idle Airflow Compensation value over time. This incorrectly learned value may cause various symptoms to
occur such as, MIL on with P1101 setting, rough or unstable idle speeds and/or engine stall.
Once the mechanical repairs have been completed, perform Throttle Body Inspection and Cleaning in Service Information, followed by
Throttle Body Idle Air Flow Compensation Reset function in GDS2.
Shown below are examples of pistons with varying levels of damage.
Shown below are several examples of light vertical marks visible on the cylinder wall.
In these examples, none of the marks in the cylinder walls could be felt with the finger tip or nail and engine replacement is not
recommended.
Shown below is an example of a damaged cylinder wall.
In this example the scuffing is wide and has removed the crosshatch from the cylinder wall in the area above the arrow.
This would result in oil consumption and requires engine replacement.
