So today my Z died going down the road around 60mph. No sputtering, just cut out. I pulled over and checked under the hood for any wires that might have fallen off or come loose but everything looked good. Tried to start it and it fired right up. Then it just kept happening more and more frequently. It always starts back up if I let the engine stop and I crank it with the starter, but it will not start if I'm coasting and pop the clutch. I tried jiggling the key thinking maybe it's a loose wire in there, but it didn't help. I saw a similar problem on here and someone said to watch the RPMs to see if it is a spark problem. The problem is, my tach decided it wants to live at 2000 all the time. So any ideas on how to check spark while driving? Timing light strung through the window is all I can think of. Also, any ideas why my tach is stuck?
Thanks,
Jake
