Nissan/Datsun 300ZX: 1995 300ZX: Driving at 75 mph speedometer 1995 300ZX: Driving at 75 mph speedometer suddenly stopped working. Power steering also stopped. When car is shut down and restarted, steering works initially then quits. Occasionally, after driving a while speedo and steering both start working again. Any idea what's going on?

 

Are you saying it idle for awhile and getting back again??

 

No. Car must be driven for 15-20 minutes, then it works. Or shut down completely, then restart it works until accelerated a little.

 

I think the problem would be the engine.
