What a flickering check engine light really means
On your Exeed TX, a check engine light that flickers or flashes is different from one that stays on steady. A steady light often means the ECU has stored a fault and wants you to investigate soon. A flickering light usually means an active misfire is happening right now — the engine is not burning fuel properly in one or more cylinders. That unburned fuel can overheat and damage the catalytic converter, so this is not a symptom to ignore.
