You are going to have to take it to a mechanic... You cant know for sure what an engine check light is trying to tell you until you plug it into a diagnostic tool.

Check engine light came on while accelerating. Barry


Take your vehicle to a local auto parts store (e.g. Auto Zone) and they will diagnose the problem by reading the *Check Engine Light" code. This is a free service.

Good Luck!

Engine light just turned on


an obd 2 scan tool has to be used to diagnose your problem , it can be something minor to something

major. a scan tool will show a defined code as to what the problem is. while you only see an engine

light. most garages and auto repair shops charge you a fee to diagnose the problem. but some auto

parts stores such as auto zone auto parts will diagnose it for free at no charge, they will even give you

a print out of codes to show what parts you may need, and will carry the parts so you don't have to go

all over town. I hope this helps you, good luck!
