Problem with golf 5 gti 2007.
When I stop after driving and let car run at idle. Car throws P2196 Oxygen (Lambda) Sensor B1 S1. Signal to high (rich)- Intermittent.
Allways when this happens fuel trims goes into open loop, all values are 0.
When this code pops up I can feel car shakes a bit, hard to start driving (manual), sometimes can smell fuel.
Some times there is P2096 Post Catalyst Oxygen (Lambda) Sensor Correction; Bank 1. - Too lean (Intermittent)
1. front O2 sensor has been replaced
2. PCV replaced
3. Spark plugs replaced
I still can't find the problem, maybe someone can help?
