You haven't flooded the engine correct, check the spark plugs. Also, how fresh is the gas? Try shaking the car to get the gas mixed up and try cleaning out the cylinders with a torch to blow out excess gas. You should also either try cleaning the spark plugs or replace them if they look bad. It is starting up fine, correct? The alternator is good, right? I believe it is since it sounds like you didn't drive it long enough to drain the battery but check it anyway. By losing power, did the electronics start shutting off first or did the engine die first as this would show whether the alternator is bad or not. Please answer my questions and get back to me on what shut off first when it died and I will help you narrow down the problem with this car.

good luck

Check your spark plugs. or your distributer., You may have a fouled plug or faulty/worn cap and rotor. The spark plug wires too can cause probs.

Engine Vibration


Low octane gas and a missfire could caused the knock sensor to send a signal to the computer which retarded the timing and caused you to loose power. When you killed and restarted it, it recovered. Maybe some new plugs are needed.

the first place to start is the flashing engine lite. that means cylinders are not firing at all or improperly and driving it like that for even short period could cause heavier damage. particularly valves and cat converter(s) the computer really needs to be scanned for codes in order to proceed. did the oil lite come on before or after engine quit. after engine quit would be normal cause it stalled. its possible that it needs spark plugs and/or coils. or more

Engine running rough


hey

As in "rough" could you be more descriptive.
i.e.
what does it do when your driving?
is it sparking on all cylinders?
any knocking in the engine?
