Just wondering if anyone knows what causes this. I bought the car brand new and it has had a rough, or should I say it sounds more like a exhaust leak or ticking sound for about 20-30 seconds on cold start ups, since new. I have had it to the dealer and of course they say nothing is wrong with it but Im thinking its starving for oil or something. Im starting to wonder if I made a mistake by buying this thing. Any help would be appreciated. Thanks, Tony.

Sounds like the air pump. Mine has a subtle rough idle at start up for 40 seconds while the air pump is running. When it shuts down and the RPM drops from 1200 to 900-100 it smooths out, but I don't hear anything.

So would the air pump make it sound like it has an exhaust leak tic. I was thinking that the top of the motor wasnt getting oil. I really cant believe for the money that I spent that it sounds like this.

I have heard people say that the air pump sounds like a vacuum cleaner, though I can't hear mine. Maybe it is going bad.

My car only has 5,000 miles and has made this sound since new and the dealer says that they cant find anything wrong with it.
