Hello, I'm Danny.

Having the check engine light on means you have a fault code stored in your vehicle's computer causing this issue. The first thing you need to do is retrieve the fault code or codes that are causing your drivability issue and low power. Here is a tutorial showing how to retrieve codes:

After you perform this then we ask you to get back to us with the code information and we can then properly diagnose your car. Hope this helps and thanks for using 2CarPros.
