Hello everyone.
I'm having an issue with my 1987 325es with an M20B27. After the car gets warmed up, it will lose almost all power and seem to stutter. When this happens, the revs stay up but the econometer goes to zero, even off throttle. If I'm at a stop, the engine will not make enough torque to move and it will have a lot of hesitation to bring revs up. I captured a video of the behavior while stopped:
Sorry for the shoddy camera work, but you can hear the rough sound of the engine while at a stop sign. After a while, the behavior resolves and I'm able to take off. The rest of the video is on the downhill, but you can see the econometer is pegged at zero in the beginning phase when the car is moving, briefly even when i'm off the gas.
My research suggests that it's the injector pulses or fuel system delivery but where do I begin diagnosing that? Most of the threads that feature this issue dead end. I'll do my best to bring it to completion.
Thanks in advance for the help.
