My 2000 Mazda Protege has abt 27, 000 miles on the spark plugs (copper ones I think).
The car seems to be idling rough. Is 27k on a set of plugs abt right? Time to change them out?
Also....what abt copper vs platinum plugs. Any real serious advantage to platinum plugs worthy of the extra cost?
I'm unemployed full time college student right now..so cost is an issue. I don't mind going platinum IF the extra cost is really worth it in reduced maint tho.
