Not trying to save money here but just trying do see how a cap / rotor age, learning and fun.
Kept my old cap and rotor and found out that the 4 terminals on the cap have some build up that doesn't go away with sanding, and one even fell out like a scale. So I use a box cutter to scrape on the terminal and sure enough all of the build up eventually fell off.
Then I sand off the rotor and put them back on the car. Ran a lot smoother and the idle rpm is about 200 higher as well.
Is it possible to keep using the cap if I clean it this way? The rotor I use have 2 fiber glass sandwich a metal plate, and the metal plate seems "burnt", so I probably have to replace it.
