I am facing troubles in CNG in my Vitz 2000 Model.
When I install that, it was ok for 3-4 days. Then in the morning it started to trouble, like i fI start the car and then press accelerator to convert that to CNG, it converts it. But IF i start driving, its like the car is JAM. the speed remains 3-4 KM and would not iincrease even if I give accelerator. But if i turn the gear to N and then gives the accelerator, it sounds great and OK. condition remain same for further 5-10 minutes, and then car start to run normally.
Later, after further 3-4 days, even after 10 minutes can did not take PICK UP. and remain on 3-7 KM and then stop.
However, it is ok on Petrol.
If i run drive the car on Petrol, and then convert that to CNG, then it is ok. But if in the morning or after a long break like 5-6 hours, i start the car on CNG it do not seem to be ok.
Can u help me about the issue ?
