Z14XE problema pornire

la 750 rpm la ralanti este perfect dupa ce s-a oprit socul electronic. problema cu pornirea este alta. vezi cu ce debit iti baga pompa sau daca prinde aer pe la tur sau retur si se dezamorseaza. stima

Un EGR blocat pe deschis dã simptomele descrise ptr pornirea la cald...ºi cred cã se potrivesc ºi cele dela rece...

Salutare, am si eu o problema cu astra g-ul meu, 2008, 1.4 benzina. Am fost in concediu saptamana aceasta, am avut masina lasata sa respire, nu am miscat-o timp de 4 zile. Cand am vrut sa o pornesc, nu a pornit decat la a treia cheie.Apoi am oprit/pornit de cateva ori , a fost totul ok.In ultima zi de concediu,la plecare, la fel, pornire din a treia cheie. Bateria nu cred ca este de vina,este noua,anul acesta este luata, alternatorul este facut de curand, nu incarca corect, electromotorul nu cred ca este de vina, se auzea ca invarte ceva la contact pus.
Azi am pus tester pe ea, nicio eroare aparuta.

In plus, pe autostrada, la viteze mari, volanul vibreaza. Mentionez ca am schimbat recent discurile,placutele, amortizoare,flanse, bielete antiruliu, insa nu stiu daca s-a facut geometria rotiilor, nu a aparut pe devizul de lucrari, si nici eu nu am intrebat.

Intrebarile mele sunt:
1. De ce nu porneste dupa ce o las nepornita o perioada mai mare de timp?
2. De ce vibreaza volanul?Din cauza neefectuarii geometriei?

mersi anticipat
