Intermittent check engine light and a rough idle on a Nissan Patrol VI usually point to vacuum leaks, ignition coil trouble, or a dirty MAF sensor. Here’s what to check and when to stop driving.
What Your Patrol Is Trying to Tell You
When the check engine light flickers instead of staying solid, and the idle feels like a shaky camper, your Patrol VI is giving you a warning, not a breakdown notice. In my years working on these SUVs, the most common culprits are small air leaks, weak ignition coils, or a tired mass airflow sensor. A flickering light often means the engine computer is seeing an intermittent misfire or a fuel trim issue that comes and goes. The good news? It's rarely a catastrophic failure, but it shouldn't be ignored.
