When I set the cruise it is "surgey" I have a direct line from vacume block to a y that goes to the ball and cruise unit. Should there be a check valve in that line? wouldnt think that would cause a surge as its in vacume, not boost. The speedo needle is not smooth, waves around a bit, maybe a 5mph swing cause the cable probably needs to be lubed but its a bitch to get to.
any help?

I am pretty sure that it needs a check valve...the one on the firewall was a check valve.
