When the Check Engine Light is illuminated, the vehicle may perform normally or it may experience issues such as poor acceleration, a rough idle, stalling, and/or poor fuel economy. In some cases, the vehicle may misfire and the Check Engine Light may flash on and off. Whenever the Check Engine Light comes on, it is important to have a Check Engine Light Diagnosis.
A Check Engine Light Diagnosis involves special computer system scan tools, fuel pressure and electronic testing equipment, specialized technician training.
You definetly need to see the dealer or qualified workshop so identify the problem and dont treat it lighlty and get it diagnose asap. Avoid long drives for sure.
