They charged total of 4000 (3600 for labor of injector and throttle service+ 400 for wd40 cleaner) and gave engine jerks as gift.
After 3-weeks
Mechanic diagnosed that coil boots are faulty and leaking currents which is leading to engine jerk at ~40-50kmph speed.
Showroom offered complete coil change(costing 54000), so i prefer to change boots, purchased from outside market which costs 3200 (2400 for boots and 800 for labor charges).
What i learnt is that suzuki showroom mechanics are FAZOOOL, they will solve one issue but will create another. Never follow the suzuki advisor instruction(as in my case he advised to get throttle and injector serviced because speedometer has completed 45000km). I should have not listened him because its cost me ~8000 rupees to get my car back to normal condition.
