Just bought a Liana. Had an issue with its FF CNG... on cng its rpm was fluctuating while idling and as it moved it had jerks ...
After one or 2 days The car started bogging down as soon as it switched to CNG.... What i could do .. I did! That includes
a. Checked its cng filter, found it Ok.
b. Drained oil thru drain nut (very small quantity)
c. Opened the kit(i think its called reducer) and cleaned it from oil traces
Then sent it to SUZUKI M.WAYS sh.E.FAISAL. They have diagnosed that ECU is faulty and responsible for this erratic behaviour.
As per them, ECU is not properly sending the signals out. As a proof they say that they have checked the car with other ECU that worked fine.
Car is OK on petrol.
Kind advice of PWs is requested.. What should i do??
