Hello guys, am already relatively desperate and turn to you , because I need the car every day urgently So for some time the yellow engine control light shines again and again with my 406er and he takes short time no more gas .. That happens again and again at irregular intervals, mostly in city traffic In idle times he goes up and down (which however does not bother me and he NEVER goes out) Me also comes before that he somehow does not his performance on the highway .145 goes just now So I was already in the workshop and the following was done : spark plugs, petrol filter, air filter, contact spray.. So 140 € away, did nothing I thought ok, I drive to Peugeot service : error memory was read out and it only came out “sporadic error mixture preparation” I asked what I should swap, he said that could be anything and the car would be old etc. (again 30 € away Yes OK, but I did not have the The car has made fresh TÜV, tires new, brakes first new…. Besides he has only 150,000 on the speedometer and runs otherwise really well, was serviced So my question: Did someone ever have this and know what it was ultimately about ?? Or what would you try next ?? I sprayed Liqui Moly throttle valves cleaner in the air pipe next to the air filter , 2 cans but that didn’t bring anything.. I also feel like he has to buy a new one. Performance doesn’t have either So I’m grateful for EVERY TIP !! LG
