I own a 1986 Nissan 300zx, Non Turbo. The digital speedometer works Intermittently.
I can be going 60 mph then the speedometer will read 0. Likewise with starting off 0 then twenty mph or whatever. Any suggestions?
There's a sending unit on the transmission. That could be bad or losing power. There's the gauge in the dash that could be bad. If the gauge was losing power, I would expect all gauges to fail.
