Faulty Speedo

Hey guys, one of my speedometers works fine while the needle in the other is sluggish while accelerating and generally shows a speed that is slower than the speed I'm actually going. I've hooked the hose up to an air compressor and blown out all of the gunk. What else could be wrong with it?

Did you blow out the hose from the speedo end? If not, you may have sent debris futher into the tube. Other than that, your pitot tube may be bad. You can get a new one anywhere for $5.00.

ya, i blew it out from the speedo end
