Hi friends, I wonder if anyone can help me. I have a CLK 200 and keep getting the engine management light on with the computer reading "Open Circuit P0130 Oxygen Sensor Upstream" I have changed the Oxygen sensor and even the Air mass sensor and it still comes back after a day or 2. I have niticed that it comes on when going around a bend and once when I went over a bump. I have sat in the car on a ramp while my mechanic shakes and moves wires and it doesn't happen then, a coupel of days later, it comes back on. It's cost me a fortune and is driving me mad, does anyone have any ideas ? Many thanks. Steve
