Ok, this is for a buddy who just bought a nice 87 GN.

First, No speedo read out on the digital dash, or turbolink, but the odometer works fine. VSS gone bad?

Also, at part throttle the car bucks real bad, seems like a real sharp miss. No miss at wide open throttle, Everything looks good on the Turbo link, no codes.
I swaped my MAF and it still did it, seems like if it was that sharp of a miss it would be ignition, he said he put plugs and wire in it, Coil pack?

VSS sounds toast, or bad connection. Also, depending on which chip he is using, no signal from the VSS could cause the car to run funny/bad.
