Probleme M20B20


Recommended Posts

am o problema la motorul de pe E12,m20b20,motor de E34 din '89

daca accelerez brusc 2cm pe pedala,intai scade turatia aproape sa se opreasca(nu s-a oprit niciodata),si apoi urca...si la fel face cand sunt in mers si scot din viteza,in loc sa ramana acul la 800rpm sau cat trebuie acolo,intai scade la 400-500rpm apoi se stabilizeaza...

 

mentionez ca:

-nu trage aer fals,mai toate furtunele sunt noi si care nu sunt,sunt verificate si nu au crapaturi

-debitmetrul,ECU,regulator relanti sunt ok-probate pe alt motor si acolo merg ok

 

au ramas 2 kestii care urmeaza sa le pun noi,chiar poate sa fie din ele? adica pompa benzina si senzorul cititor din fata de pe fulie(motorul are 1 sg senzor)

bobina de inductie poa sa dea simptomele astea?pt ca uneori nu scade usor turatia spre 500rpm,ci scade super rapid acul la turometru dupa care urca
