Hi All,

I bought Santro Club GV in December 2005 and it worked perfectly fine since then, I used it many times for outbound journey and i dont have any problem at all. Total millage of the car is around 33,000 Km.

Recently the car has problem that when i try to start the car on petrol it failed and start missing horribly and when i convert it back to CNG no problems at all. I visted many times to the local dealers and every time after inspection they told me that my car dont have any problem at all. But when i'm driving the car if i convert the car on petrol it work fine some times and some times it start missing horribly and i'm forced to convert it back to CNG.

I went for normal tunning of the car and my spark plugs are fine but it does not make sense to me that why its working fine with CNG and not with Petrol.

My conclusion is that it may have some problem with Senser that causing the problem but when i go to workshop there are no symptoms at all. If sensor is out of order then why its fine with CNG?

Any Ideas????

what's CNG?

CNG Stands for Compress Natural Gas. In west, its also known as Propane.
