Regardless, you ought to have the vehicle checked by a specialist. In late-model vehicles, a flickering light, as a rule, shows a motor discharge failure so extreme that unburned fuel is being unloaded into the exhaust framework, where it can rapidly harm the exhaust system, prompting a costly fix.
