NOTE: This condition will only appear when the engine is started from cold and the engine coolant temperature is 75°C or lower.

SITUATION:

When the engine coolant temperature is 75°C or lower, poor engine running, hard starting, rough idle, and/or an engine misfire may be evident. Additionally, the engine Malfunction Indicator Lamp (MIL) may be illuminated with Diagnostic Trouble Code (DTC) P0316 and one or more misfire DTC (P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, and P0308) stored in the Powertrain Control Module (PCM).
