I think it's the actual speedo this time. It has always acted wierd, no movement till about 20MPH then jumps up. Needle shakes to 30 MPH, then gets smoother. Looks like I got to find a fuel pump and a speedo. The car is pissed that I drove my other car! I'm telling you, these things get jealous if you play with something else!
First, did you lube the speedo cable at all? This sounds much like a binding speedo cable to me. 80's/90's VWs have this problem a lot.
As for automotive jealousy, that's pretty common, too.
