Loss Of Power-O2?
 

2002 SLK 230
Got the check engine light. Reads out P0130 and P0131 - Oxygen sensor.
Additionally, when warmed up it intermittently has a loss of power as if the fuel flow is stopped but never turns off. After a few seconds it returns. Very scary when pulling out into traffic.
Local shop finds nothing except the O2 sensor and history of a misfire.
Question - will this sensor failure cause an intermittent losss of power? If no, any ideas. Sensor to be replaced tomorrow - on order.
They also tell me that the computer does not give nearly as much info as other M-B's.
Thanks for any insight.

Get the MAF cleaned too.

I have used carby clean sparingly and compresed air to dry.

Oil mist gets thru system and contaminates sensors.

Thanks bazzle.
That was discussed with the technician yesterday. The car is going in tomorrow AM for the O2 sensor swap out. I will have him do that. It only makes sense to me that it has to be the MAF because it is intermittent.
Yesterday the car ran fine until I went up the local interstate at about 85 mph and the damn thing misfired a couple of times. Everything was fine again until I stopped at a red light and it started misfiring big time. Then the check engine light came on again. Everything fine since then.
We'll try it and thanks for the assistance.
