I have a 99 2.4l alero and when im in drive and when i stop at a stop light or stop sign its like a hard vibration coming from the motor like it wants to die and when its in neutral or whend its really cold out it runs/ idles fine, any help would be appreciated thanks

Have your wheels checked for balance. That is the small weights on the rims. If it is not balanced, you will feel the steering wheel vibrate. It can also be a bend rim. Have the tires checked at a tire shop.

Are you using high grade gasoline? No ETHANOL mixture! Give it a try, it may get back to normal.

You may have front brake rotors which are slightly warped. The ABS only comes into play under very hard brakeing conditions. Typically you may also feel a slight pulse in the brake pedal as you slow down.That would be my best guess.If you have a vibration when you are stopped, that may be a motor mount issue. Either the front and/or rear mount may be weak.They are designed to isolate small engine vibrations you might feel when the car is at a stand still The motor mounts are designed to isolate small engine vibrations at a stand still at idle as well as limit the amount of travel the engine can make under a load. As a car gets older, the rubber which is what the mounts are made of get harder and often collapse slightly and can cause your condition because they are no longer plyable.Maybe this might shed some light on your problem. Good luck.

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.

It sounds like your a/c compressor is getting ready to lock up.

try changing your cv axels/ drive shaft

sound like you have a cylinder not firing properly, a tune-up would be the first thing i'd try

Sounds like you have warped rotors and or a lose caliper mounting bolt . When you stop do you feel a vibration in the brake peddle or in the steering wheel or both ? IF you feel the pulsation in the brake peddle I would suspect a brake pad / brake rotor problem . Now if you do not feel it in either and the vibration is through the whole car with out the brakes being applied i would think it may be related to and engine/drive line problem (motor mount /trans mount /axle problem)

it would be a good i dear to have it scand.that would help you pin point the prolbem. look at your cv joint you may have one going bad. good luck

does the rpm motor kick down? you may need to check your vacuum hoses, and also you may want to check your exaust, sounds wierd but that can cause the car to stall at times.as for the traction light, your hitting the brakes to hard. try slowing down a little slower while stopping, and keep distance for saftey.. if you can take it a little slower at lights and turns, without braking hard and it stops stalling.
