Salut,

As dori si eu un sfat deoarece am intalnit un lucru straniu...
Intre 2000 si 2400 rpm de sub motor se aude un zgomot metalic, un zdranganit ca si cum ar fi un colier desfacut. De cand se aude zgomotul a inceput sa mi se aprinda beculetul rosu cu injectorul urmand ca el sa se stinga dupa cateva minute de circulat. Zgomotul e prezent intotdeauna intre turatiile mentionate mai sus dar becul cu injectorul se aprinde mai rar.
Aveti ceva idei ce ar putea fi? Sa ma astept la vre-o sonda lambda sau ceva?
Mentionez ca am o Alfa 156 1.6 TS din '99.

Salutare, cat ulei consuma masina? cand ai schimbat ultima oara bujiile? De asemenea cand este rece afara ( sub 18 grade ) daca o accelerezi mai brusc, scoate fum ?

Un filmulet cred ca ar ajuta... Din ce zona provine zgomotul?

Nu scoate fum, am masina de 4 luni, nu am schimbat bujiile. Papa cam 1-1.3 l la 10k.

Zgomotul provine undeva intre rotile din fata, am ridicat capota si nu se aude nimic straniu de la motor in sine. Am impresia ca ar fi ceva de pe evacuare... Zgomotul e ca un colier de metal care joaca pe o teava metalica... dar nah... la evacuare nu prea stiu sa fie existat Colier metalic :)

Zgomotul nu e de la motor in sine. Am verificat.

S-ar putea sa fie in catalizator sau o tablita desprinsa de pe undeva si la anumite vibratii sa se auda, daca nu provine de la motor.

Merci de sfat, cum apuc sa o urc pe rampa / elevator va anunt. Am o rampa fix in fata blocului dar e facuta pentru logan cred...inainte sa atinga rotile rampa dau cu spoiler-ul de beton :)

Nu e nevoie de rampa. Se poate verifica cu capota ridicata.

Sorry nu mi-am dat seama la ce te referi... protectia aia e prinsa bine, nu joaca, nu vibreaza...

Pune-o pe rampa si verifica traseul evacuarii, verifica prinderile catalizatoarelelor in special.

Scuze pentru raspunsul intarziat, am urcat masina pe rampa si am identificat zgomotul. Era un suport de tabla inaintea catalizatorului. Se rupsese surubul si a ramas "liber" pe tubulatura.
