So my service engine light came on (flashing for some reason, not on solid) and my X started to lug when it at idle. Like going 5 mph it felt like you were tapping the brakes. I don't know what would cause this and the search function wasn't working right now. I do need an oild change, but don't see how that would effect the car. Everything seems fine as I can drive fast and go through all of the gears. Just when it gets down to idle speed it seems to lug along.
Any help would be appreciated as I am quite concerned. Thanks in advance.
