I just bought a 2001 530i, knowing it needed a few things. It has a rough idle but the tach indicates a relatively steady RPM. (It feels like it might die at any moment.) Also, this morning I started it up and there was a loud ping sound from the engine that pinged about every 5 seconds, it did this for about 2-3 minutes and stopped. Can anyone give me some suggestions?
