Misfiring

Hello,

The first step would be to scan the vehicle and retrieve the code(s) for the check engine light.
It could misfire for having worn spark plugs but it could be due to other components as well, like bad coil or module.
Do you happen to know the code(s)?
If not, you can take it to your local auto parts store and most of them have scanners and they will scan and give you the code(s).

Here is a helpful guide:

The EPC and ESP are likely related to traction control issues. Which can also be scanned with the right type of scanners to diagnose the cause.

Please let me know what code(s) that you find.
Thank you.
