Motorul opreste uneori la relanti la viteza mare

ma refeream la cum e mai bine sa fie EGR in momentul in care va fi scos (pe deschis/inchis).
Ca ma gandeam sa nu reactioneze diferit ECU si sa memoreze ultima pozitie a EGR-ului si sa continue amestecul ca atare...
Asta daca nu cumva are un amestec standard in conditii de EGR debransat/ OFF

mi a spus cineva ca situatia cu depunerile de calamina de pe clapeta de acceleratie se poate repeta la motorasul care trage aer pe tubulatura (de la filtrul de aer).

cica si acest motoras are o clapeta ca la acceleratie pe care se poate depune calamina, si asta ar putea fi cauza simptomelor mele.

Cum mi-a mai ramas putin spray de brake cleaner, nu ar strica sa fac nici aceasta operatiune, avand in vedere ca niciuna din cele anterioare nu a dat rezultate.

Intrebarea mea este: unde este acest motoras care trage aer?

Salut, nu , nu credeam, dar nu strica sa incerc, poate fi ceva plauzibil, am ridicat capota si am vazut mufa la care faci referire, eu am tins sa cred ca este vorba despre

ce am facut cu sageata rosie acolo.

Oricum, e clar ca exista un motoras care trage aerul, ca nu se targe singur(asta in cazul in care nu il trage chiar clapeta de acceleratie, dar clapeta de acceleratie doar il primeste in admisie)...doar trb sa aflu unde e

Salut,

Am sters erorile si am mers iarasi cu masina.
Fara sa apuce sa se manifeste, am verificat de erori cu un soft de android:
Apareau 0300,0304,0400 (ceea ce mi-a apaurt si anterior.):

Mi-a scos aceste doua rapoarte, in timpul primului motorul murind din senin.

Apoi am pornit inregistrare paramentrii motor si am mers cu masina pe autostrada, scotand-o din viteze la 110 , 90, 80, si 50 la ora. Mi-a murit aproape de fiecare data.
Mai mult, mi-a murit si la un 20 la ora.

Am decuplat EGR si am pornit iar pe autostrada, facand acelasi lucru (scoatere din viteza/lasare pe liber la diverse viteze).

In 10-15 minute de plimbare, nu a mai dat nicio simptoma, nu a mai murit motorul si nici nu a mai mers infundat cand luam piciorul de pe acceleratie.

Multumesc anticipat!

pai deja era suspectul principal...dar ma gandeam sa nu fie si altceva...cu toate ca erorile de missfire, cum spuneai si tu, pot fi date si de un EGR faulty care saraceste amestecul

Pai... se mai oprește?
Te asigur ca mufa scoasã la EGR nu înseamnã cã s-a reparat. ....

Pai, ai bec aprins? Da....
Ai nevoie de EGR nou si ai rezolvat si problema asta.

Eu unul zic ca tu nu intelegi situatia.
Motorul tau se opreste uneori si merge neregulat - identificat problema, EGR defect. Ai de cumparat alt EGR nou sau SH sau poate mai suporta ceva curatare al tua cel defect.
Mai departe, logic ar fi sa cumperi alt EGR, dar mai poti merge cu mufa scoasa de la EGR sau mai poti sa o tragi pe dreapta....

Nu reusesc sa ma exprim corect poate. Abandonez.

Daca din toata discutia asta (si multe altele de pe forum) atat ai priceput, atunci incearca sa ii cureti si roata de rezerva..., poate ajuta...
