Probleme De Ralanti - Ford Thunderbird

[siscrew]

Salut !

 

Nu sunt posesor de Daewoo, dar am fost indrumat spre forumul acesta de o cunostinta de pe motociclism.ro, si sper sa ma puteti ajuta.

 

Masina e un Ford Thunderbird Elan din 1985, iar motorul e pe injectie CFI, adica are 2 injectoare centrale, e unul din primele sisteme de injectie.

E un V8 de 5 litri, si imi face ceva probleme : porneste la cheie, dar nu tine ralantiul, moare daca nu il tin in ture. Evident ca nici nu se pune problema sa merg cu masina in starea asta, asa ca ma tot chinui sa ii dau de cap. Deocamdata am testat senzorii, si am schimbat cel de temperatura a aerului, dar fara nici un efect vizibil. Am descoperit insa ca daca o pornesc cu acel senzor decuplat, ralantiul ajunge la 3000 de ture, si baga si rateuri, evident ceva ce nu imi doresc. Are careva vreo idee ce-as putea sa-i fac ?

 

Mai jos e descrierea care am pus-o pe unul din forumurile ford, nu prea cunosc termenii echivalenti in romana pentru unele lucruri.

 

Rebuilt 302 engine with headers, crane cam, the bearings are all new (10 over on crank), new hyp. pistons (9 to 1), (30 over on cyl walls), oil pump, heads had to be shaved a bit as right head was slightly warped, new valve job, with new rod guides and hyd. lifters. It is a ford CFI throttle body with a computer control module. It will start and I can keep it running if I keep throttling the gas, but will not go to an idle no matter how warm the engine gets !

I replaced the Air temperature sensor on the engine, as it was showing 2.7 volts with a cold engine, while the coolant sensor was showing 3.2, but to no effect. If I disconnect the air temp sensor, the engine will start and run at around 3000 rpm, with the occasional backfire before I shut it off.

 

Any ideas what might be causing this ?

 

Multumesc anticipat.

Probabil are un debitmetru sau iac dus sau vreunul din senzori da informatii gresite.Cauti un scantool pe ebay pentru ford sau manualul de reparatii cu datele aferente pentru toti senzorii care ulterior pot fi masurate si verificate.
