I'm afraid my fat guy is really worried about me.
in recent times he consumes quite a lot (17-20l) although he runs round (otherwise 12-15l).
I've thought it might be the lambda probe...you hear it often

Can you check the thing, or do you have to buy new ones in well-done?
In addition, the thick one sometimes has a noticeable loss of performance, it turns the gears up, but until it comes out of the ass passes away. the big puzzle I am that this noticeable loss of performance is not permanent
Sometimes he runs like a kitty and gives full performance, and sometimes I step on it and nothing happens. ==References== are connected to the lambda probe???I'm a bit at a loss - please help, you always have great tips at the start
