Some Nissan Sentra owners report experiencing rough idle and acceleration issues, which may be attributed to bad ignition coils. These problems can manifest as vibrations in the cabin and symptoms such as engine hesitation, loss of power, and excessive fuel consumption. Additionally, many owners have noted that the check engine light often illuminates as a warning sign. Common causes for rough idle include vacuum leaks, spark plug issues, or ignition coil malfunctions. Some owners have encountered recurring problems with ignition coils burning out unexpectedly, leading to persistent misfires that can severely impact vehicle performance. Misfiring is frequently identified as a primary cause of rough idle, emphasizing the need for prompt attention to ignition coil issues to ensure optimal engine function.

A significant vibration with moderate braking at highway speeds may develop on vehicles stored outdoors for 3 months or more. This condition may be due to corrosion on the brake rotors. Our technicians tell us that normal driving for about a week should eliminate this issue.
