hi, i got a Daewoo Racer, engine is quite xtra ordinary in its performance but for the last couple of months, it started troubling on CNG. early in the morning the pick is ok and the car runs well but after few hours, the more i push the accelerator the more the car goes down in speed. according to the electrician da car's whole cable system needs to be replaced so if there's any possibility to fix it up without doing so, do lemme know ; )
