on? I already replaced both O2 sensors, (rear and front) and the fuel filter. There doesn't appear to be any damage to the air intake compartment, no holes or leads. The MAF appears normal, secure and clean. I have no idea what's going on.

The traction control light is on, the car jerks on acceleration.

The car has 82,000 KM on it.
