Hi All,
I have honda city 2005. Recently it has started to give this issue on CNG (on petrol working fine). When on neutral, the engine try to auto accelerate, mean as soon the RPM goes below 1, then engine accelerate itself to increase the RPM to go between 1 and 1.5. Any idea whats wrong. I checked with a mechanic and he said the CNG sensor needs adjustment.
Thanks in advance.
