HI/LOW RPM Problem

BHR-370z

Hello Everyone,

Has anyone encountered any of the below problems:

[1] HI RPM (slightly above 1000):- sometimes when I keep switching between the S-mode and Normal drive mode the RPM seems to be stuck at a range slightly above/close to the 1000. This however gives you the feeling that someone is slightly hitting the accelerator instead of you and thus affecting the breaks as you need to completely step on the clutch to prevent such effect while breaking (it happened to me 3 times now). [Note: the effect is not very dangerous as it is very predictable and anyone can control it because you can feel it easily. However, it worries me much].

Anyway, on the 3 rd time I took the car immediately to the local dealer here and they ran a check over the car and informed me that there was no technical issue at all and they have adjusted the RPM (^_^) great I said however, NOW I have ----

[2] LOW RPM:- (almost near 500):- the car seems very quite while it is not moving because of the low RPM, however when you are about to make a complete stop the RPM sometimes drops to almost below 500 for a second and comes back to the same level again (this feels like the car is about to be turned off) my guess is that this effect is mainly because of the low RPM set by the car dealer therefore I might need to take it back to them to slightly adjust the RPM again.

Hope someone can help me on the above issues and it would be great if anyone had managed to adjust the RPM by himself instead of taking the car to the dealer and would like to share the process with me?

Thanks and kind regards
