Major CNG Problem on Newly Converted Vehicle

Its a 96 Japanese Automatic Corolla. Took it to Al-Mubarak for conversion a week ago, problems ever since first day of conversion. On return they say such and such with the engine may be messed up etc, so go to so many mechanics who say everything is fine nothing to do etc upon return told to go to another mechanic, getting really tired of this.

Have taken it back to Al-Mubarak 3 times for tuning again and again and to other mechanics as well, total of 6 times (everyday since conversion). Problem pops up again same day.

Problem:
1. On CNG, push the accellerator, the car just wont go, then after a while starts crawling, and after a while longer starts going. When at higher speed, when push accelerator, very long delayed response for pick up.

After having it Re-tuned from a seperate mechanic, it works great for a day, next morning/evening again the same problem occurs. Sometimes when leave the house, or sometime at intersection it dies out as well (car stays on but just wont move), retune, than drives great.

Configuration:
landi renzo, along w/advancer and regulator etc.

Any ideas wats wrong, as sick of the run around go here go there this problem that problem game!!! Help would be greatly appreciated.

Hello!
i think spectra bhai was almost right...incorrect mixture + make sure plugs are not old nor wires......!!!and they are giving good spark...
by the way 96 Corolla...is that AE101 or AE110 one????
comes with 4EFE,5A-FE and 4AFE.........
i think they came with Distributor Type Ignition and won't need any advancer!!!!! Just emulator is needed.....!!
anywayz.......Spectra was there to solve that...don't worry..
Thanxxx
