Astra G Z16SE 0300 error

P0300 - Multipe cylinder missfire. Adica nu ai scanteie la bujii , aleator. Verifica in prima instanta bujii, fise si modul de aprindere. Masina mananca ulei?

Cum zici ca merge normal, sterge eroarea si vezi in cat timp reapare, daca mai reapare.

hat does this mean?
OBD Code P0300refers to
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly. A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms
Possible sumptoms of OBD code P0300
the engine may be harder to start the engine may stumble / stumble, and/or hesitate other symptoms may also be present
Causes
Possible causes of OBD code P0300
A code P0300 may mean that one or more of the following has happened: Faulty spark plugs or wires Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector(s) Burned exhaust valve Faulty catalytic converter(s) Stuck/blocked EGR valve / passages Faulty camshaft position sensor Defective computer
Possible Solutions
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

salut, iuly
Masina.merge perfect nu am nici o problema cu ea ( dimineata porneste putin mai greu )dar in rest nu are nimic. Am crezut ca am eu vreo problema cu masina de consuma asa mult ) . Ma gandeam ca este de la bujii de consuma asa mult si de la termostat+pompa de apa ca nu am apucat inca sa le achimb

pai am citit ca eroarea aia 0300 este de la buji si cred ca daia porneste greu ca nu le-am schimbat pana acum. Merci de sfaturi

P0300 parca is rateuri multiple pe cilindrii.
Cauza de obicei ECU. Mai poate fi bobina de inductie, mai rar bujiile, defect intern in motor si foarte rar injectoare.

Incerci cu alt ECU...
Uneori se repara.

mie masinuta imi merge perfect. Consuma putin cam mult adica 10-11 % in oras . in rest este ok

merg normal nu sunt genul sa conduc sport. eu am impresia ca chiar consuma foarte mult ( in oras
