market reputation of chinese coils is 50-50...some say they work some say they don't...an former manager of suzuki motor said that chinese coils work fine as compared to used original coils from bilal gunj...my mechanic say that chinese coils are pathetic,used one are better....so at the end i took a chance and buy chinese coils...and they are working very good in my car...
1200 RPM seems very high at idle condition...it should be around 850 on CNG and 750 on petrol...that can save fuel and produce less noise at idle...but if your car is giving problems then 1000 is good enough...and remember one thing always try to avoid RPM setting form throttle screw...never do it...some lazy mechanic dont work to stabilize the car by fuel setting they just screw the throttle and say every thing is fine
about the Kharadia cost i m sorry i have no idea how many he take for what work...i fact i also feel it high because the individual costs of all job done by kharadia told to me is less than the total cost that is written in bill...and u know what
im not going to pay it:P(H)
