Hello everyone.
I have problem with my car.Check engine comes on after i give more than 50% throttle.On cold start the car shakes for about 15 sec.When the car is fully warmed up then it goes away but i feel on the throttle that there is some resistance when i go up the revs.The diagnostic throw these codes 29F5 29F5 2A9A 29CE codes which i read on forums that are O2 sensors bank 2.But which one?
The one after catalyct converter or before?
Or is it something else
Also i replaced both exhaust and intake camshaft sensors and cleaned vanos solenoids 3 months ago so i dont thinks thats the problem.
