I just got a '77 280 Z. At the time of purchase it was only running on #2 & #3

cylinders. After I got it home and and started it again I pulled the wires from the other plugs and it ran the same.

On #2 and #3 I changed the plug wires and still the same. Next I took a good distributor out of another one of my Z's and still ran the same.

I pulled the coil wire from the cap and held it to the frame and it had a strong consistant spark.

I am using a D6F4-03 distributor which was in my '75 280 and the one out of the new car is the same.

Right now as the battery is being charged I am going to change the transistor

ignition unit.

Does anyone have any other ideas? If you would like to e-mail me: terimdc@yahoo.com

Did you pull the plugs? I thought that would be the first thing to check.

You did not mention anything about a distributor cap either.
