Good afternoon, I drive a Mazda 323 BG with 1.6 8V (B6-E). Unfortunately I have since bought the car strong vibrations in the interior, as soon as the vehicle is at operating temperature / idle speed (approx.800U/min). It has been so extreme that I have temporarily increased the idling speed a bit, because if you give some gas to approx. 1000-1100 RPM the vibrations are actually completely gone or not to feel any more. Due to many forum reports and the fact that my 323 also at I now had all four engine/gear bearing replaced. Especially the bumping felt as if the engine was tilting back and forth. It was a good decision, because the rear bearing was definitely defective and the others also didn’t look very nice anymore. This tilting now seems to have disappeared, but unfortunately not the real problem, which bothers me much more – n The vibrations. These have remained almost unchanged.. Now my question would be, what else could this be? The engine runs absolutely round for my feeling, turns up nice and does not cause any problems. Every now and then I mean to see that the speed is going up and down a bit (only minimal), but that may be because I have adjusted the idling a bit (could of course be undone at any time, but the vibrations would be I have now read that the ignition setting or time of ignition could also be considered for such a thing. But can this cause so strong vibrations without having strong rotational fluctuations or false ignitions? Especially since the current AU test is absolutely inconspicuous. Only with the “actual value” of the ignition time nothing is entered, only the “toll value” of 7 +/-1 degrees v.OT. With the rest there is everywhere. Otherwise there would be possibly still wrong air, whereby I auc h here would rather introduce strong speed fluctuations as a companion. I unfortunately don’t know any more, but I absolutely have to get that away, because it is so simply not fun to drive the Mazda. MfG
