RPM unstable in Liana RXI FF CNG

On CNG my Suzuki Liana's RPM is unstable when applying clutch while braking. It drops below the idle 800, sometimes below 500 and the 'engine problem' light turns on momentarily before the RPM raises back to the idle 800 RPM.

On petrol, this doesn't happen and RPM stays steady at 800 when idle.

The spark plugs are brand new, and gaps adjusted properly. CNG has been tuned electronically. Air filter cleaned. Dunno what else to do.

Other than this problem, pick up on CNG and consumption are good.
