My vehicle was 207 1.6 hdi 92 hp Injector and turbo maintenance was just done 1 week ago, it was very good lately when I was loaded on the gas, it throws excessively black smoke. FatihBall2020-06-14 14:35:46

What did the place that made my teacher, did it pass over the injectors with that important break or just stamps etc. Simple maintenance was done with my repair kit. high fuel consumption airdebimeter etc. it might be a problem. but possibly injectors like troublesome again. also check egr.

Okay teacher i got it
