Salam, I have Suzuki Alto VXR reg 2008 FF CNG. Used only 22,200km. I am having pick up problem on CNG especially with the AC on. Even without AC I am having late pick up on CNG. I got my car tuned on CNG but still I am having the same problem. My cars intake is blocked 60%. I also have suzuki mehran it has a small engine as compared to suzuki alto but my mehran has excellent pick up on CNG. My mehran's accelerator is much hard as compared to my alto. Does this have something to do with pick up problem?
Secondly my car shakes after 70km/h.
Please suggest me what should I do.
Your suggestion will be appreciated.
