already dealt with the coils earlier , car was missing on 2k rpm only , Suzuki 3's said coils will be changed and quoted some 20-30k i dont remember exactly, I showed it to my mechanic he took out coils cleaned the springs and closed the coils with silicone let them rest for like 2 mins, put them in and voila the car runs smoothly, whole thing didn't even cost 500rs
my personal mechanic is near commite chowk,
