how does the direct injection work? A link to another thread will work if there is one. Steve, what is the throttle blade?

 

well i don't know what noise hes speaking of, mine make a few, this is why i offered my opinion on the noise.

 

direct injection puts the fuel right into the cylinder, instead of through the intake manifold.

 

As far as the click 5 seconds after shutoff, i always hear it too

 

From what ive heard the "dropping" noise after the car is shut off is the throttle body closing all the way. Its completely normal on our cars

 

the sound that always gets me is the "sloshing" from the dashvoard, sounds like something circulating

 

the sloshing sound i have found in most cars is low radiator fluid.

 

A few seconds after shutdown the throttle closes with a "clunk", that might be the 2nd sound. I had asked the same question a while back, but don't know how to post a link to that thread?

 

Yup, a lotta "funny" noises comin from my SS either while idling or after shut down. I look at it , like was said, that it's better to hear the noises, than not.

On a cold start i hear a noise that will drop out after a few minutes,, since i use remote start most times, i get in the car just about the time that noise ends.I use that as my proper time for warmup (prob 3-4 minutes or so)

I know it's ok to give a lil bit of time running b4 you put it in gear, but i expect to get a few hundred K miles on this one, just like most everything else i have driven, giving that i put 600 miles a week of what i drive, so i prefer to let it run what i consider a good amount of time. Out of my driveway it's 55mph, and the after 10 miles, it's 70,(for the next hr) so i really don't have the chance to take off kinda slowly

I took a mental note of what noises i hear during start up /idle/after shut down, so i think i hope to be able to catch it when one does not happen, or one or a new one pops up , THEN i'll worry

 

I hear a whole bunch of noises during idle. Even my wife asked me if that was normal. I said "of course honey, it's a turbo - those rocket scientists at GM know what they are doing." :)

I also hear the flap closing a few seconds after turning off the engine.
