could this be possible? recently hindi maganda yung idle ng auto ko. nacheck ko yung distributor and found na may leak sa loob. this was a problem also before pero nasolve nung pinalitan yung oil seal sa loob ng distributor at nagpalit ng sparkplugs. so thinking it might be the same prob, di ko na pinarepair yung distributor. instead pinalitan ko na ng surplus pero di ako nagpalit ng spark plugs. pero ganun pa rin. rough idle. yung sparkplugs around 1 month old pa lng. ang question, can the faulty distributor damage/affect the sparkplugs?

thanks in advance sa replies!
