Ummm Jumping Speedometer
So I noticed this issue shortly after I bought the car exactly one year ago. I back out of my parking at home, put it in drive, go to drive away, and the car sputters like it would if the traction control was on and the wheels were spinning on ice, the speedo jumps clear to 140 and holds there until the car stops sputtering, Iím clearly not going 140mph. What the H is going on here. It happened again today and itís starting to freak me out.
