... I have no idea how to remove the rotor on my '90 Accord's distributor so I can test the coil. Any guidance would be greatly appreciated!

If they're the original coil and igniter, I would definitely replace, not test, them. Use this time to install a new rotor and distributor cap. Personally, I prefer Borg Warner distributor caps, which come with brass (not aluminum) contacts. Their caps and rotors have a lifetime warranty.

Thanks very much. Fortunately I still have contact with the original owner and can verify the age of the parts. However, at first glance, they don't look like parts that have provided service for the 230.000 mile life of the vehicle. (I'll ask anyway, just in case they are original.)

Can you tell me where I may be able to learn more about how to remove/replace the rotor if/when I get the new Borg-Warner brand parts?

Thanks again for your assistance.

Get a 1990 Honda Accord Haynes Manual, which is available at most auto parts stores.

Thanks! Got one, but I must have missed
That section. I'll check again. Appreciate
