As Salam Walikum,
I have a santro 2008.. i am facing quite some problems when running on cng now. i need serious help.
First is that Cng milage has gone down.. i barely get 115km in full tank (6.25kg) without AC in the city.. Secondly the pick is not that good too.. third is that when idling on CNG, there is a lot of vibration in the car.. i got my injectors serviced, my throttle body serviced and the sprak plugs & air filter changed but i am still facing this problem.. on low rpm idling the vibration is so much that all passengers feel it..
When i drive, upon slowing down, there is a massive drop in rpm of the car, i noticed it in night driving as the lights suddenly dim when i approch a turn and slow down the car, as i put my foot on pedal, the rpm goes back to normal..
What can be the issue or issues.. what is to be done.. please help..
