when the sensors are disabled ...

Hello friends, I have problems such as wobbling in my car, I do not eat gas, the car is working with rich mixture, it throws black smoke, it even throws unburned gasoline. My car does not have gasoline lpg. oxygen sensor and pressure sensor changed, the problem continues, but when these 2 sensors are unplugged, everything gets normal and the sensors have just changed. What should I do? This problem can not be solved. Vehicle 106 gti 1998 model

don't you have any idea about the problem

I have checked the vehicle's ecu, hodja. you have replaced the sensors, so I can disconnect the ecu and check the sockets. because the sensors you said are connected to ecu
