CNG related problems

[Suzuki1]

i think u dont get my point mate
tell me some thing how manifold play a roll in back fire?? as far as my info is conceder the back fire in car happed when there is lack of may mixture in engine exmp:- air,current or fuel this thing cause the back fire in the engines mainly CNG car do back fire due to improper fuel and air mixture this air ratio thing can be due to many factors like exmp:- old air filter,blockage of air filter pipe etc now a days cars manufactures use predefined distributor setting for low fuel consumption that why KIA SPECTRA,SENTRO ,BALENO,LIANA ect all those cars which have predefined distributor setting
make fire back prob if u can change the advancer setting of those cars at on accelerator (if u dont know how to doo that or have some prob in doing that i can also help u in that)
so if u do that then when the owner of a car press the accelerator of the car then advancer on and advance the setting of distributor doing that u already giving the car a air mixture as well as fuel then a car find a proper current mixture as well then this fire back prb will gone this is the hole story which im trying to explain to u in my above post

Thank you

@fyq
I have a khyber 97. BRC kit is installed in 2004, from six months the car's race could not be adjusted on cng, we had to pull the choke to increase race so that the engine must not stop. The vibrations are there, and increase with ac, some mechanics adjust rpm others race and some the gas flow, but not useful.
I also changed the air filter but it could also not help.
How can the cng be set so that we do not have to pull the choke? and secondly, is there any need of cylinder and kit service due to oil in it, as 60k has been done on cng?

O O O !
to many problems , ! anywaz no need to be worried, i m there for u ppl

BALENO!SEAHAWK
first of all yeh ke plugs check kerwwao, and also advance ur car's current by mechanic, and 170 pe woh balenos jati hain jo 1.6 hon, aam tor pe 145 on petrol is a bit less, but not least ! jaldi conversion k liay ksi cng mechanic se kaho, woh swith se adjust ker de ga, jaldi shift ho jaey gi.BAQI A GENERAL TUNE UP WITH ANY SKILLED GUY IS REQUIRED..

MAWAN!
power T se gas and air ka mixture adjust hota hai.

WAHAB!
kit ka slow mixture kit khulwa k change kerwao, wese brc parts are rare to find, milta hai to theek hai,werna bataana,i'll do smfin 4 u. ya thora sa distributor se advance kerwa lo gari ko, tub bhee theek ho jae gi.

THINKDIFFERENT!

Dear FyQ!
I bought a city iDSi 2005 model, 27K km driven and on Petrol with NO CNG installed
I have installed LandiRenzo CNG kit with 55L cylinder, and LendiRenzo STAP78 Advancer and Emulator from GASTEC, Satelite Town by Waseem.
My car runs fine on CNG giving me 135-155 Km per filling.
As soon as I started the AC, the idle RPM started to decline and finally to 0 and the car switched off. Without AC, everything is fine and also there is no problem on Patrol.

The other problem is that when I am on idle, AC is ON, and I started to put the car in move in first gear, I have to push accelerator a lot, otherwise the RPM drops ans engine turned OFF.

I have replaced the plugs, got throttle body cleaned from Honda service Center, RWP, and then get tuning from CNG installer.. works fine for some days or so then same problem appears....

Any permanent solution to this problem or suggestion for any expert CNG mechanic in Islamabad/Rawalpindi ?

some of the friends at PW suggested to reduce the air flow.

Your expert opinion is required in this regard

SILICON!
cng lagana, and cng pe chalana, dono different kaam hain, u must asked them to installl cng. pehle me yahii kahoonga ke jis ni install ki hai us ko he bolain, jub woh hands up ker de ga, phir meri bari, got it? game of some bucks and some minutes.

@fyq

As you've suggested above for tunning, even after tunning i'm facing the same problem. I'm feeling some increase in pick but sometimes it looks like engine is going off then i've to push accelerater hard to keep it turned on. ????
