Ahhh good to know that....
But here is my story....after so many months my Liana got the chance to run on CNG... and for the very first time in almost 3 years I am not happy with the performance of the car on CNG. It gives jerks, and die down on turnings...and you have to wait (lift the foot from the accelerator a little) and after few moments the MA13 wakes up
So experts what do you suggest...is this something to do with the CNG kit (FF) or CNG filter or the injectors .... on petrol the car is as good as ever. By the way it is a 2006 RXi, with FF CNG and is driven around 87k. And I never faced any such issues during the last 3 years, it was driven 56k when bought from the first owner.
