Got the car scanned yesterday after work since out of nowhere it felt sluggish, shifting was a lil weird and speedo didnt seem accurate, like it said I was doing 55 but felt like I was at 45mph. Code 1 was p401 EGR code, I hear I can take that off and spray carb cleaner into it to clean it out which could troubleshoot it for now but would that be correct and what else could I do? Car just feels sluggish and dosent pull like it should it even sounds a bit louder but I could be paying attention to it too much. And second code was for I believe my wheel speed sensor would that be the culprit for my speedo and shifting issue? And would I be ok driving it for a few days til im off on Fri?
