    Tolin, sunt speriat mai ales din cauza ca am folosit exclusiv benzina de 98 si uite ce am gasit pe net:

     

    01-027/02

    GM Tehnical Bulletin

    1995 - 2002 Millenia (KL engine) - MIL ILLUMINATION WITH DTC P0300 TO P0306

    APPLICABLE MODEL(S)/VINs

    All 1995 - 2002 Millenia models with 2.5L V6 (KL)

    DESCRIPTION

    After a cold start, MIL comes on with DTC P0300 to P0306 stored in the memory. In most cases, this concern may be caused by misfire occurring in one cylinder during idle. The use of premium fuel (high-octane fuel) may be allowing carbon deposits to accumulate on the exhaust valve seat, causing momentary insufficient compression.

    To correct this concern, remove carbon deposits using a suitable top engine cleaner.

    NOTE : After removing the carbon deposits, be sure to advise the customer to use lower-octane fuel (87 or 89 octane) to help prevent future recurrences. REPAIR PROCEDURE

    1. Warm up the engine until it reaches the normal operating temperature, then turn the ignition off.

    2. Locate the canister purge vacuum port into the intake manifold to feed the cleaner into the engine. This allows the cleaner to distribute evenly.

    CAUTION: ^ Be sure to feed the "Top Engine Cleaner" into the engine through the correct vacuum port.

    ^ Do NOT use a PCV hose. If too much cleaner enters the engine, the engine may be damaged.

    ^ Do NOT use the vehicle vacuum hose. You have to prepare a new hose and fit an orifice (E5B6 13 986) into it to limit the suction rate.

    ^ With an orifice fitted into a new hose, about 7.5 fluid ounces will be fed into the engine, taking at least 1.5 minutes or longer. If the cleaner is fed at a faster rate than 7.5 fluid ounces per 1.5 minutes, excess liquid entering the cylinders may cause hydrolock, resulting in engine damage.

    3. Fit the other end of hose into the container of "Top Engine Cleaner".

    4. Choke off the hose with locking pliers (vise grips), then start the engine.

    NOTE : Large amounts of exhaust smoke will be emitted in the next step. Be sure to connect the exhaust evacuation hose to the tailpipe and ensure there is adequate ventilation.

    5. While cycling the engine speed between 1500 and 3000 rpm:

    a. Remove the locking pliers from the hose with the orifice. The intake manifold vacuum will now draw the cleaner from the container.

    b. Monitor the feed rate. Only 7.5 fluid ounces (half can) should be fed, taking at least 1.5 minutes or longer.

    c. When almost 7.5 fluid ounces has been fed into the engine, reduce engine speed and allow the engine to stall. If the engine does not stall, turn the ignition off.

    6. With the engine off, wait at least an hour (not more than 24 hours). This allows the cleaner to soak into the carbon deposits, increasing its effectiveness.

    7. Repeat Step 1-5, using the remaining portion (approximately 7.5 fluid ounces) of the cleaner.

    NOTE: Do not allow the engine to stall this time.

    8. Remove the hose with the orifice and reconnect the canister purge vacuum hose to the intake manifold.

    9. Test drive the vehicle 3 miles or longer to completely remove the remaining liquid and carbon deposits from the engine.

    10. Perform engine oil and engine oil filter replacement service.

    NOTE : With new engine oil and filter in the engine, start the engine, then raise the engine rpm several times to circulate the new oil throughout the engine.

    11. Verify repair.

    NOTE : Be sure to advise customer to use lower-octane fuel (87 or 89 octane). Periodic use of a well-known gas treatment (such as Chevron Techron) can be recommended to help prevent future recurrences.

    Se dau:

    - aveo 1.2 cmc

    - 3700 km

    - mers turat

    - euro 98 rompetrol

    - pus de 3 ori aditiv curatire supape liqui moly

     

    Problema este ca din intamplare am observat teava de esapament si am vazut ca este acoperita la capat de funingine atat pe interior cat si pe exterior putin.

     

    Intrebare : este normal? voi asa aveti la ale voastre?

     

    Chiar nimeni nu s-a mai intanlit cu acest fenomen?

     

    O fi din cauza benzinei de 98?

    sau a valve cleneru-lui

    Nu stiu de unde stia. Cert este ca era convins de ceea ce spunea si de faptul ca problemele de pe motoarele de 1.4 si 1.6 se datoreaza aceluiasi lucru, si anume ca ne sunt trimise niste rebuturi de care nu se intereseaza nimeni, softul la ele fiind facut pentru benzina din germania(luata ca etalon).

     

    PS se pare ca benzinele reformulate sunt o problema

    Omul mi-a zis ca este foarte important sa fie facuta asa cum a zis si tolin. A zis ca masinile care vin spre romania, bulgaria si ukraina nu au facuta nici o procedura. Mi-a si aratat pe scanner faptul ca toate valorile erau initial in 0,000 lucru ce este, dupa spusele lui, teoretic imposibil pentru ca numai intr-o lume perfecta am avea dintii volantei la acceasi distanta dintre ei, micronic vorbind. Valoarea de 0,000 este setata standard din fabrica fara a mai se regla pe masina. La momentul respectiv nu am inteles la ce e buna procedura sta dar dupa ce ati spus voi am mai inteles cate ceva.

    Bine...de aici nu pet sa trag decat concluzia ca ar trebui sa fiu mirat si de puterea scoasa de matiz la cilindreea de 800. Nu m-ai inteles. De ce in raport cu : 1.4 vw 16 valve scoate 85 cp sau 1.2 16 valve fiat scoate 80 cp, motoarele daewoo scot din 1150 8 valve 72 cp? S-a facut cumva ceva sa le creasca puterea in dauna fiabilitatii?

    Tommy nu trebuie sa fii asa dur. Explica oamenilor ceea ce tolin a vrut sa zica. Baieti tolin s-a referit la faptul ca puterea motorului conteaza mai putin intr-un drum virajat si cu serpentine, unde este foarte importanta stabilitatea masinii si abilitatea soferului. Ne dor mainile sa scriem!

     

    Extrapoland: chiar aseara la emisiunea TOP GEAR pe un drum pe serpentine din sudul frantei au testat un Ford de 450 cp, o Zonda tot cam asa si un Ferrari de 320 cp...ghici cine a iesit primul...zi tu Tommy.

    Am observat ca in acceleratie "sustinuta" pe la 4000 rmp masina are tendinta de a da in nas pentru o fractiune de secunda si dupa aia isi da drumul. Facea inainte pe la 2000 rmp dar se simtea mai putin dat fiind faptul ca acceleratia era mai slaba.Dupa reset nu mai face dar in cateva zile dupa ce se obisnieste cu

    turatia de schim a vitezelor iar face. Adica in momentul in care schimb am 3500 rpm si cade in 2500 rpm, din momentul in cere se obisnuieste cu acest cilclu incepe sa faca din nou.

     

    Aveti idee ce se intampla? Face ca si cum ar taia benzina pentru o fractiune.
