My 98 Civic misfires just once and very intermittently,usually while driving at highway speed and maybe just once a day.The check engine light flashes for that brief second that it misses and then all is well.I replaced the distributor with a used one and the problem still exists although,it seems that the miss is now more subtle.I suppose the second distributor could be bad too.Any thoughts?

 

just replace the cap , rotor, plugs and plug wires, (a tune up)

 

new distributors off rock auto starting at 69 without wires, cap or button. 129 with previously listed accessories, and i agree with replacing wires, plugs, button and cap.
