Loss of power and not accelerating properly

Hello, I'm Danny.

Is your Check Engine light on ? What we ask you to do is perform a CAN scan to retrieve all code information from your car. A CAN scan will test all the systems on your car including the any issues you've mentioned. Here is a tutorial showing what is involved for a CAN scan:

After performing this procedure get back to us with all stored code information and then we can properly diagnose these issues with your vehicle. Hope this helps and thanks for using 2CarPros.
