Va salut, recent mi am cumparat un bmw e46 din 09,2002, 318i cod motor n42b20a. De vreo luna de cand o am mi s-a intamplat de cam 5-6 ori. Masina are anumite momente cand nu isi tine ralanti, porneste in 5-600 rpm si scade pana moare, nu pot sa o accelerez, nu raspunde. Pe bord nu am nici o eroare. De regula, dupa ce moare, a doua cheie porneste fara nici o problema. In rest dupa ce se intampla treaba asta masina merge super bine nu are nici o problema, nu simt pierderi de putere sau altceva. Niste idei? Cam asa face: https://www.youtube....h?v=E39PBkKTqbo .

1. ori distributia sarita de la punc si admisia/evacuare sunt decalate;
2. un senzor de sub admisie.
sau vreo bobina ...

multumesc frumos de răspuns. Fostul proprietar mi a spus ca a schimbat distribuČ›ia acum 1 an jumate, ce i drept uitându te la ea prin capacul de la ulei pare ok. O sa iau toate variantele in considerare Č™i o sa merg sa fac ceva. Am văzut ca face când este motorul rece, ieri când ploua nu a mai vrut sa pornească deloc. astăzi o sa schimb pompa de benzina pentru ca am impresia ca cedează Č™i o sa incerc sa le iau prin eliminare, multumesc.

da, si pompa de benzina cand e pe duca ...face asa.(intra si ea in piesele care pica)
verifica si carcasa filtrului de aer care intra in clapeta de acceleratie...e putin incomod de verificat, dar arunca un ochi si pe acolo.(vezi ca e si un furtunas mic, ai grija sa nu il rupi)
