I was driving my 2010 GT today and I just kinda noticed that the exhaust was sounding somewhat lopey.. I revved it and the rpms went down much quicker than usual and the speedo jumped to about 10 mph when it was revved.. (the car wasn't moving). Should I be worried? What could it be?

 

Be very worried. I think your stang is possessed.

 

hahahaha. that just made my day.. but it's been acting kinda funky. now today it's all good? i have a p1000 code, but that's nothing to worry about...

 

I would have it checked asap

 

got everything worked out. it happened when I was in reverse on some ice. but nothing is wrong and everything is all good!
