catalytic converter and antipollution fault

Emergency help. I have 307 gasoline vehicles in 2004. It has not been 2 months ago. I traveled quite super 2 thousand km without any problem. but the car had a traction difficulty, especially on slopes. Then one day while driving in the traffic, the car started to shake and stopped while stopping at the red light. At that moment, at least 5 km on the road, the car stopped 10 times. vehicle on the slope. I parked the car in the garage and then said I would run it two days later, the car did not work. I called the master who installed the gas. LPG is not related to the job, you have the coils checked the ignition system. the tool works very hard, stops at home and writes antipollution fault and catalytic converter fault. please help me. What should I do? In this case I am in Ankara. Do you have a master to recommend? is this caused by lpg? :S

I don't understand LPG more but sn. As cecoli always said, your vehicle should run normally on petrol, then LPG is expected to run normally. Since the master probably did not work on the gasoline, he could tell you about possible error points. I think that it is necessary to connect your vehicle to the computer and see where the error is. Of course, a subject that is frequently seen in these LPG systems will already be expressed by other friends.

your car's catalytic may have been filled, depending on it, it may be giving the solvent, disassemble, clean or replace it, look at the oxygen sensor, it may possibly recover.
