AoA.hope you are all doing good.
today while cleaning engine bay i mistakenly closed the inlet manifold of air filter box for a bit ,i expected the engine to stall immediately but it kept on idling smoothly..
Then i firmly close it with a help of cloth , it didn't stall but vibrate a little.
i took the car to Adil Zafar motors.they say it's normal,car will only stall when it's on CNG...i was like :o..
i doubt there is certainly an air air leak..
car is suzuki alto vxr FF cng.
throughly maintained by SUZUKI 3S.
engine oil zic A+.
