ISSUE:
A hard start and rough idle after cold start in ambient temperatures may occur on some vehicles. Hesitation/stumble/engine induction backfire or stall
may occur after start during cold engine performance. The Malfunction Indicator Lamp (MIL) may illuminate and Diagnostic Trouble Codes (DTCs)
P0300, P0301, P0302, P0303, P0304, P0305, and P0306 may be stored in continuous memory. This may be caused by poor quality fuel in combination
with hardware operating at the minimum or maximum specification limit.
