Chances are that a heat shield located under your exhaust or the catalytic converter has broke loose and rattles when you are idling in drive. This is common on older cars and is only usually noticed while idling in drive because the engine is working under a slight load and runs a little rougher. A good exhaust shop could probably fix it for very little.

SOURCE: engine or transmission knock / rattle upon

I had the same problem on my 2006 Lucerne and it was the engine mount located on the front of the vehicle behind the radiator.

SOURCE: My car makes a rattling/vibration noise - under the Hood when I am sitting idle at a light or parked (while running) - Only notice it happening when the Car cooling fan kicks on and my Air conditio

Airbox is not latched down properly. I had the exact same problem. I found the front of the airbox was clipped down but the back was bouncing up and down and making a racket at low idle. There are 2 clips on the front of the airbox and none on back. You have to put the rear of airbox down first and insert rear into the plastic slots to hold it. Then you put the front down and clip it down.

What could be causing rattling under the hood when sitting still?

Many things can cause your problem but the most common is either a heat shield or a retaining clip that has come loose. My recommendation is to block your wheels so that your vehicle can't roll forward, open your hood, start your vehicle, HOLD YOUR FOOT ON THE BRAKE PEDAL, have an assistant listen to see if they can locate the noise. If the noise is gone with the hood open then look for any shiny spots on the underside of the hood.

My car is making an awful groaning grinding noise noise when it starts. The noise stops after it starts. Put my foot on the brake it starts again. put thr car in reverse no problem put it in,drive it...

It's your exhaust mounts or broken exhaust bolts. It does it in drive st idle n under load because the motor is sitting in rubber mounts made to dampen vibration. Therefore the motor tilts to the left in reverse pulling the exhaust away from your under carraige, and to the right in drive causing the loose exhaust to vibrate against something. Check your heat shields also. They fall apart n do the same noise. Piece of cake.

Car will not crank

If you can locate the starter,tap on it with a hammer a couple of times then try to start up.It may take several tries but it should work eventually because a starter doesn't usually fail 100%.If you can't locate it call around,someone will tell you for free because they want your business.Dealer,shops,whatever.Good luck!

My saturn SL2 died at idle...and now wont crank over...there is juice to the starter and the battery has 13.1 volts

Any starter clicking noises? Try moving the shifter to "N" neutral and try starting the car.
IF that is not successful, find the starter relay in the under-hood fuse box, replace the relay with an identical relay from the under-hood fuse box and see if it will start. This will then eliminate the park/neutral start switch and the starter relay.
Let me know what you find.
