The culprit is usually shot piston rings. They act as a buffer between the combustion chamber and the bottom half of the engine. If they go, oil can seep into the combustion chamber and get burned up along with the fuel. To fix this, they'd have to take the entire engine apart to get at the bottom of the pistons. It's not a cheap procedure. Or maybe you're ...

I would not consider this an issue. What is happening is, as you've probably already figured out, is that your car is adjusting itself to the higher altitude. When the light comes on, it is telling you it is basically out of calibration (probably due to running too rich at the higher altitude). Once the computer can get caught up and adjusts the fuel map ...

After the belt warms up a little bit, it sticks a little better so the sound goes away. If you haven't replaced the belt in a while, I'd ...

They have less surface area that actually comes in contact with the brake pad, so the net effect is that your brake pads are "smaller". I think you might have two ...

Also, how are you doing the brake test? I have hawk street pads and if i speed off in the mornings from my cold start, and THEN hold my brake, i better not ...

I had the same problem with my car last year, problem only occurred when idling and not while driving. This is why I immediately suspected the IAC. Removing and cleaning the IAC did the trick for me. Hope this will help you.
