Dear all,
I found this forum and want to ask people if they have similar problem what my car has. Im not speak russian very well, but I can read your answers.
The car is: octavia II, 1,6 BSE, 220k km (maybe even more).
Problem: the car lost the dynamic speed (I know that all this engine anyway not so strong under 2500 rpm), especially over 80-90 km/h. Even to take over a truck very have for the car. In the city the car drivable well, but feels it was stronger. The idle is stable no shaking. Also start up well any time. Approximately +1-1,5 liter gasoline takes/100 km. There was only 1 fault code: p0420. if I know well this code means the catalytic converter under threshold or the second oxygen sensor not property works, but has no effect on the power of the car.
Some days ago I disconnect the oxygen sensor (the first one) and get back the power. I think not all the power came back but much better and also the fuel consumption went down.
My question: do you think the oxygen sensor is fault or can be other things behind like MAF sensor? Or both?
If one of you had similar problem, i would really appreciate to share with me.
