[QUOTE=mnwrali;4656410]In continuation to our discussion I would like to bring your attention toward one of the incident I observed 2 days ago.
As usual I stared my car and converted to cng, despite the cold weather (8 : 00 am) the car remained very calm, no vibration (peace of mind) and very settle rpm of 1200/1300.
This is very rear condition but happens quite often with my car. Usually this condition remains for couple of hours or until you restart engine after some drive.
Fortunately I took an 45 min drive to my office via liyari expressway almost touching comfortably 100-115 km/h in 4th gear, didn't even think of using 5th gear.
This condition of the car remain almost for 2 days, every time I took the ride to drive it gave the best performance which leads to the question , why can't she remain for the same all the time?
So I decided to go for the physical inspection my self, what I notice that the air box hose was slightly removed (half attached and half away) from the throttle mouth and loose clamp. Which may be letting more air into the throttle and letting engine breath without any interruptions (without any air filter).
I physically inspected the air box which is not really in gud shape with broken air box clamp and tighten with the wires and screw.
I would like to ask that is there any possibility of faulty air box?
Yes it could be,make sure venturi is properly fixed on inlet manifold and air hose + air filter assembly properly air tight,there should be no air leakage.Make sure air filter is neat & clean.
