Couple of days ago I revd up my car while waiting for the light to turn green and I noticed that when the gas pedal is pressed hard the engine knocks.<br>
<br>
It was a little weird since it would stop responding when it came aroud 4 or 5 thousand rpm and fall down to around 3 thousand rpm and then pick up again.<br>
<br>
Has anyone seen this before. The problem happens only when my car is in neutral. <br>

Your engine is equiped with rev limiter that<br> disallows exceeding 5000rpm in the neutral, to<br> protect torque converter from excessive forces.<br> I think there's nothing to worry about. My<br> C320 is behaving in the same way.<br>
