same as most, start up and drive off with a min or so. Don t push it until temps are up.

FYI/997.2 One time I stopped to talk to someone and left the car running for maybe 10 mins , don t know lost track of time. Drove home maybe a mile and put it away. The next day I left on a long ride and when I got there and looked at the rear of the car it was very black from the exhaust. Only happened that one time and I assume it had something to do with the long idle time the day before.

It's called...C4S Play....get it?
Enjoy the warm up.
Like sniffing wine.

I pretty much do the same thing everyone is doing. Idle for a minute or two and take off...Once the oil temperature reaches around 200f, I put it on sport....and the fun begins.

ellery is infamous around these parts
the increased idle RPM at startup is to help warm up the catalytic converter quicker as it only really works when hot.... driving off before that happens means that your ECU will be running a richer fuel-map as it's not getting accurate feedback from the O2 sensors.

I idle for about 30 seconds before backing out, and keep RPM down until oil's hot as others mentioned.

I start it up and drive away with light throttle and stay below 3K rpm until the oil temp hits 200F. By the way, the popping exhaust sound on the 2005-2008 models during a cold startup is a result of the late ignition timing combined with the exhaust air pump needed to get the catalysts up to temp asap to reduce emmisions. The DFI engines do not have an air pump.

My 2009 C2S makes some wild noise when is cold. Within 30 seconds it comes down an becomes tamed. I have a Tubi exhaust system.

I think all the waiting for the idle speed to drop does is waste gas. The engine is configured to be run at higher revs to compensate for the coldness of the engine, but driving off is what its designed to do as soon as you crank it and the engine fires.

I know! I hate to interrupt it by driving off so quick!

If your worried about that small amount of gas burning in a 45-60sec span you might wanna invest in a hybrid?

Ahh, it turns out this is a religious topic (wink). This is probably not rocket science as some of you gently suggest. I'll go with my gut and at least wait for the fast idle to reset, maybe that habit is a hold out from my recently divorced hotrod days letting the carb clear after starting up. Running the engine rich for no good reason feels wrong. Correct me if I'm not right about this.

just look that way because of the video camera - they don't really strobe.

Yes...but it really is an old post (even though it says 2011). No longer is there "one man, one engine" manufacturing so I'm sure there are other factual errors in the write-up also. I just had the factory tour this summer and the engines do go down an assembly line - it's a pretty efficient process. Also, I don't think the Boxster and Cayman are made in Finland any longer. Still an interesting read though. Thanks for the link.
