After a lot of Research and Surveys i have found at last the perfect solution for liana engine jerking,missing and pick problem especially on CNG.
The solution is to remove the factory fitted CNG kit as this kit is the source of all problems in CNG performance of this car.
We have installed a landirenzo EFI kit in my friends SUZUKI LIANA car who has a lot of problems in CNG earlier now each and every problem is solved its an easy process and will cost you almost 8000 to 10,000 Rs but you will feel the real performance of this car i bet.
We havent seen any difference in fuel consumption as now its more better than earlier and dont ask about its pick and speed in CNG as its become more lighter and faster so keep my advice in mind and just remove the factory fitted kit and enjoyyyyyyyyyyy.
comments will be appreciated so as i can discuss furthur, and also share your experiences as this car is flop due to its engine but if this cng Problem is solved so i dont think that its a bad engine, it only gives problem in cng mostly and now above is the solution for it.
