Idle Ripple

My friends car 206 XT 1.4 16V 2005 model, I had the problem of stopping in my car, it was lpgli, it stopped when it was wasted, something called calibration was done in the special service and my stop problem was fixed, but they said the catalyst was broken, the oxygen in the OBD II kit was showing the sensor was defective and I changed it code has been deleted. The other error code was p0140 and they deleted it while calibrating. However, after my car warms up, the cycle is experiencing a drop again, I checked all the values in the obd II kit and I add the photo of 02 volts Bank 1 sensor 1 and bank 1 sensor 2 fluctuating too much, what do you think is the reason? Could sensor 2 be faulty ?? In the meantime, there is no problem in the traction of the vehicle, the exhauster said that if the catalyst was defective, the vehicle did not. a lapse 2020-02-07 23:11:33

First of all, the reasons for your vehicle's speed to fall are generally manifold cracks, throttle position sensor malfunction, if your vehicle is at lower speed dead upper speed, your catalyst has completed its life. How often did you change your spark plugs after installing lpg?

After I bought it, I immediately replaced the spark plugs, the throttle was cleared, but the gasoline has the same problem.

then the oxygen sensor is sending incorrect information. Because the sensor that adjusts the air-fuel mixture, check your wiring, and when the oxygen sensor fails, your vehicle's draw will not drop.

How much money did you spend on your vehicle?

A lot of money is gone males3f
