 Problems with the RPM
This is very weird!! Maybe you guys have an idea what can it be. From time to time, the RPM is going crazy, and it has a constant variation from 600 rpm to 1500 rpm and back. Beeing an automatic, it's very annoying when i'm stopped at a red light, i have to keep the break on, and the car is "dancing" up and down...I can't feel it when i'm driving, only when the car is stopped with the engine running. But i can feel that some power is lost. This is not happening all the time, and i couldn't figure a pattern for it. I don't have any check lights on, and last week i made an engine test at a BMW authorised service. They didn't find anything, cause in that moment, rpm was steady, at 600...From what i know, it could be a lot of things causing this: Oxygen sensors, injectors, fuel pump...If you have some ideas, please, i'll appreciate it. Thanks.
