A sound that's coming from the bottom of the car

There is this wierd sound that is coming from the bottom of the car, it kind of sounds like the exhaust is broken or somthing, but it kind of goes away over 3000 rpm. also the check engin light is on too, does any one have any idea what the problem could be?

If its a sort of rattling it could be that the cat has broken up inside. You would have to get the car up and secure enough to dunt the exhaust with your hand listening for any rattles around the cat area. Make sure exhaust is cold first. Catalytic converters get well hot. It may just be some heat shielding around downpipe area or cat. If the problem is linked to a broken up cat the lambda sensor may be faulty to. Might be completely seperate though so best fix rattle first then find someone who has a code reader. You can buy OBD scanners fairly cheap on ebay and the likes if need be.

Sounds like an air leak-vaccuum leak- check vacuum hoses and intake manifold gasket. Sounds like the engine is pulling in more air than it should.

Try cleaning your terminals at the battery, even if not corroded. In my years as an alarm/radio installer I have come across this problem constantly, especially on GM vehicles.

In the cold driver door does not open


as wierd as this sounds, where the door meets the car at the rubber seal, rub canola oil or some kind of cooking oil, it does not freeze and the door will not stick to the car. Another problem can be that the check strap, the little strap (usually looks like a little metal bar that comes out the front edge of the door between the two hinges) gets sticky. White grease can help that sometimes.

You are most likely hearing metal on metal on the brake pads. The brakes are not attached to the gear shift in any way. Unless those Koreans have done some really wierd design.

My scooter makes wierd humming noises


This sounds like (passing) resonance -- a natural phenomenon. You might be able to eliminate it by just tightening some bolts in the exhaust system -- or, it may never go away, or it may stop of its own accord.
