@fyq

Sir, please share the difference between FF CNG and AM CNG fitting wise, installation, and what is the main difference, or simply why one should go for FF CNG?

@horse rider !
bro ! fitting is gud in ff cng...
as per components AM cngs are better
in small cars space isnt lft for luggage in ff fitted cylinder.
not good after sales service for ff cng vehicles( specially in efi cars).

Thank you for help.

As in AM almost all the sensors are not working as compare to petrol in EFI cars, so in FF the case is same or they make the sensors to work.

The light on the extreme right is not working, can i replace it or change the whole switch? from where to change the light. please help.

thanks

@strikerx!
bro ryt now not sure abt cost, milage will be around 80-100kms on local and 150-170 kms on long n even more if u drive calmly. 2ndly a/c will effect it aprox 10kms/cylinder.
@horserider!
no need to change the switch...its mostly due to mis-adjustment of sensor on the cng kit.

bor car is charade ....4age silvertop hav 4 air intake throttles so its difficut to install and then tuned..can u help in it??

[fyq]

@saqib!
bro these simple jits can giv a good performance on 4age, however, oyrsa kit has a model wid multi outputs..which is currently not available in pakistan. i dont remmber the exct model number, but its in my knowledge. cng systems has vast number of components for diffrent kind of engines. if we install any mismatch model in engine, it will not produce the require3d or desired output and performance. a common example can be seen in factory fitted cng n liana... thts sequential type of component.

@fyq

@fyq
I suspect my car cuore FF Cng is mixing petrol when driving on Cng. Petrol needle drops slightly within a few days on Cng and petrol fumes are smelled occasionally under the hood. Also when cng switch is in middle position the engine keeps idling roughly.
Please suggest possible resolution

[fyq]

@longdrive!

The petrol solenoid valve looks something like this, I think its electrically controlled. How can I check if it is open?

[fyq]

theres a valve manual opening and closing here. chk it is properly shut. n bdw.. if ur car is mixing petrol and cng, u cant drive it smoothly...i.e there would be aloooot missing...
