@aesthete
Yes the white is mine and I saw ur car from the gallery. No doubt ur car is in excellent condition. I also saw you wearing T-Shirt and trouser am I right? If I know ur name I'll surely happy to meet with you at the hyundai workshop bz I know ur nick but ur nick is also very difficult. so can you pl. tell me your name? Thanks for your guideline .. the problem is with the reducer. Mr. Nadeem - Mechanic, which is really very very good for all the CNG issues, No doubt u guide me at the very best of ur knowledge change it with the BRC Brand which used in Santro. The problem of breating while on CNG is finished. Thanks GOD. and thanks u all ppl for for ur guidance.
@spectra
I'm really feel very bad and I'm a bit angry with you. bz.. when i share the problme with you. U did not respond to me.. only aesthete respond to me and give me the guidlines. Actually I feel and I trust that u must help me in this regard. but when u propose Re: "Spectra Mini Meet" I don't like either bz.. how can I come and meet when the car is in a critical position... I like ur suggesstion re: meet but...at this point of time when i'm in trouble how can I meet?
Now when I see your comments of May 4, I feel relaxed and I feel happy that my trust on u is not wrong.
this is the same trust that I call u before buying the spectra. and I done the same as U told me. GOD Bless You.
Actually this in not in mine case, All the forums ppl. trust on ur valuable comments. So pl. continue with the same spirit and zeal. PPL at pakwheels loves you. 
@agreessive_looks
Please share your full problem at the forum. If it is 100% same like mine... then u must change the reducer. Mr. Nadeem already changed 10-11 reducer of spectra with the BRC brand which comes with the Santro.
