I just bought a Suzuki Liana RXI 2006, Factory CNG. My car does not pick-up acceleration specially on CNG specially in 1st and 2nd gear. When ever there is a slope to climb like going on bridge the engine dies out and RPMs drop. The RPM also drop when I role out the car from zero acceleration in 1st and 2nd gears until slowly the car accelerates and the RPM cross 2300 then the car behaves better. Can anyone guide me what the problem is and how and from where to get it rectified, plus how much it is going to cost.
