I want expert opinion reg said issue. I have cultus VXLi 2009 with a manual T installed instead of stepper motor for CNG. Does it make any difference in car performance or mileage?
Secondly driving in CNG I always have a light missing whenever I am below 2000 RPM in any gear but iy becomes smooth when car accelerates over 2000rpm. Is it due to manual T part sincw I jave replaced plugs n modified cng setting repeatedly?
