off the accelerator. Why? This may have first occured after I got 2 brake pads replaced. Then I got the other 2 replaced. Does that have anything to do with it? If not, what is causing this?

Thanks, in advance, for your help, people

I got the first 2 brake pads around 4 months ago; the last 2 were replaced around 3 weeks ago. This slowing down had happened since the first new ones. It may be unrelated.
