Perhaps I'm just getting too sensitive but on cold start this car produces a symphony of sounds. Depending on the outside temerature I hear the bearing sound, a rpm dependent taping noise and a air leak type noise. Sometimes all together and other times some but not all. I also notice that start idle is about 2000 rpm dropping to about 1200 and then on accasion jumping back up a bit until it settles down to 1200 again. Warmed up the engine idles around 900 rpm.
I have the M level tune.

Anyone have similar sounds etc.? Are they normal or are there adjustments that need to be made?

Thanks for your help :o

 

all normal. rpm tapping - MOP operation

air leak- airpump doing its emissions job

 

the symphony gets louder if you have an aftermarket intake setup

 

Ah yes, The well known "Renesis Symphony" (Number 13B) in A sharp. I know this because many people tell me I have A sharp car.

The unique thing about the Renesis Symphony is that it only has three movements, each with a revolving theme. My favorite passage is the 9K cresendo. I wish the adagio section was bit more powerful but all-in-all, a true classic.

Seriously, as Zoom44 noted, these are typical warm-up notes. The fast idle is to quicly warm up the catalytic converter to meet EPA requirements.

 

Not bad.

 

Terrific and entertaining responses. Put a smile on my face this morning.


Thanks

 

When I come to park my car after driving for about 30 minutes I heard what kinda sounds like a bass sound coming from a speaker from the back bottom of my car, but when I stop I already have the radio off. Then when I get out I heard little noises by the exhaust under the car. Are these sounds normal?

THanks, my car is only a week old.
