Important
In the next step, there will be a 6-digit number stamped on the spark plug. The first 3 numbers are the date code.
3. Inspect the spark plug for a date code. Refer to the illustration above. 203 = Date Code 3 = Year 1 = Line 1 = Shift.
^ If the date code on the spark plug is 154, 155, or 156, REPLACE THE SPARK PLUG. Inspect the rest of the spark plugs and replace the ones that have the date codes 154, 155, or 156.
^ If the date code on the spark plug is NOT 154, 155, or 156, the spark plugs are not suspect. Reinstall the same spark plug. No further inspection is required on the rest of the spark plugs.
4. Install the GM Recall Identification Label.
