Ok Dr Benz I am going to do just that. Thank you for your reply.

OK, throw those wires in the trash can and get a full set of metal core wires. That is your problem.

OH man, I just installed these:

No good?  What's a good set to buy instead?

K&K sells the set that's perfect for our cars.

Thank you Dr. Benz - I have just ordered a set of copper core wires from Authentic Classics. Do you think those Bosch Plugs are resistor type and I should replace those as well?

Teahead,  those wires are the copper core wires, they should be fine.

You can change them if you want or wait until next change. The plug wires are more important.
