@Ocean i changed yesterday all 4 plugs wire,so as i put super bosch single pin brand new plugs aswell...which suits CNG...and petrol both,
i expereince another thing when ever i Push The Accelerator lightly so its fine with the Rpm no missing or jerk i get(talking about when car remains in rest) but when i give sudden HARD accelerator so i see it gives double sound from 0-1 Rpm and it i felt that Engine's Power is blocking somewhere,sounds get hard,
some time in same setting last night maximum the RPM reaching was 4 than on very next accelerator it was reaching maximum 5.5-6 RPMx1000
its beyond of my kan whats happening with it,though there is no Valves fault,No Smoke,No Such heating,Neither any cam shaft sound coming,from engine,mashAllah engine is awosom,just this HANGING on 0-3 Rpm,on CNG really messing me up..
due to which when i drive so few USTAD JEE sort of machenics said me change the clutch plates lolz i laugh inside,because its my 8th dolphin but this kinda problem is 1st..lol i can judge the clutch pressure plate thing,but i dont think clutch/pressure plate plays role when car is standing in rest,on rest its missing,i also tried taking out Petrol pipe from carborator but its still no use...
Waiting for any CNG EXPERT for reply....
