I searched the archives for jerky cruise controls but got nothing. I'm sure I'm not the first guy to get this but I thought I'd throw it out to pool the great experience base of this forum.

My cruise did not work so I sent the amp to performa to be rebuilt. They had it back to me in 5 days!

Cruise now works but is jerky.

My speedo is a little bit wobbly at slow speeds (below 40mph) but higher speeds seem quite steady.

My flex disks are new and in good shape.

Any chance this is something other than the speedo cable?

Any suggestions on cable replacement?

Thanks,
