The faster I go, the worse my speedo is off. It seems to be ok until about 40mph or so. When Im about 80, it reads 100, and gets worse the faster I go. Now, I dont know which part I need. Here are two parts that Coincelli is tellin me. Which do I need?

EDIT: The link isnt working right. Basically, its tellin me there are two parts... Speedo cable - $21.61, and a speedo head - $97.93.

Mine has been doing this since its gotten cold out too. If i'm pullin 3200 rpm's in 5th (should be about 70mph) i'm readin about 120 on the speedo

I *think* its because of the cable but i'm not sure.

I have the stock wheels and stock wheel size. It just bounces all over once I hit about 80 or so.

Sean485... You might really want to check yours. If your speedo is reading waaayy over, then your odometer is going wayyy faster than it should.. Thus giving your car more miles than it should have.
