my brother drives a 94 ex coupe and right now it has stock wheels on it with 195/60/14 tires and he is claiming that his speedo says 5 mph faster than he is going in town, and that when he is going 55 mph his speedo says like 70-73 mph doesnt make much sence to me but he swears its off by that much, all i could think of is tires, but they are stock? any ideas?

 

vss could be crapping out. try to find another one and swap them out.
