CHEVROLET OPTRA SPARK PROBLEM

2005 Chevrolet Optra • 14 miles

Hi, I own Chevrolet Optra from last 1 yr. I have fitted CNG kit around 3 mnths back. Initially it gave me a mileage of arnd 17 km/kg without any issues in pick up. However now I am facing problems with pick up. I took it to a mechanic & he asked me to change the spark plugs/cables. I replaced it. But still its giving me problem in pick up & mileage. Also, car gives hiccups sometimes. Is it due to the defect in spark plug cables?

Normally when cng is fitted to a car you have to up the compression to get power, scan for codes and see if yo have anything there then check for leaks on cng system at engine.
