Saturn Sky check engine light on with engine miss and gas smell after changing spark plugs on Saturn Sky

Some Saturn Sky owners report experiencing issues such as a check engine light, engine misfire, and a gas smell after changing spark plugs. These problems may arise from various factors, including bad ignition coils, spark plugs, or spark plug wires, which can cause misfires that trigger the check engine light. Additionally, a gas smell could indicate potential fuel system issues, such as a loose gas cap or problems with the EVAP system, and may also be linked to spark plug issues affecting the engine's firing process. To address these concerns, owners are advised to conduct diagnostic testing to identify the root cause of the misfire and gas smell, and to seek professional inspection from a certified mechanic for accurate diagnosis and necessary repairs. Regular maintenance, such as replacing spark plugs every 100,000 miles, is also recommended to prevent future occurrences of these issues.
