I would not want to change the idle for just the sound.I mean its kinda there for a reason ya know, to properly warm up the engine. If its too much of a problem maybe get a quieter exhaust. Sucks to live in a condo, I guess.

 

You cant adjust these settings yourself...you have to talk to your tuner about it.

 

I asked the dealer they said its suppose to warms the sensers up faster..-

 

This is probably not the case but just for information - when you have an 02 sensor going bad, the car will rough idle at start-up for 30-90 seconds every time on startup - cold or warm start. If you expereince this on all start-ups cold or warm, it is a good idea to replace the sensor.

 

I don't have a noticeable issue at startup, but sometimes during stop and go driving (when stopped at a red light) the revs go to 1000 and drop to 700. And back up again and down.
What could be a cause of that?

 

Check the TSB list - there is one for it.
