About four things to do, first check voltage at horn with key on and button pressed. If voltage there try moving the small gap screw back and fourth a few times. If that doen't work replace horn. If no voltage check fuse and horn relay, you should be able to hear the relay click when you push the horn button, If not and fuse is ok. Switch relay out with another on on the car. If that doesn't fix it check the horn button for continuity.

IT MEANS THAT YOUR OIL LEVEL IS VERY LOW AND NEEDS TO BE FILLED. CHECK THE OIL LEVEL WITH THE DIPSTICK IF EQUIPPED. IF NOT, THEN ADD 1 OR 2 QUARTS OF OIL TO SEE IF THE OIL LIGHT GOES OFF. IT MAY TAKE SYNTHETIC OIL SO DON'T PUT CONVENTIONAL OIL IN IT IF YOU SEE A MOBIL 1 SYNTHETIC OIL RECOMMENDATION STICKER UNDER THE HOOD. IF YOU ARE UNSURE THEN BRING IT TO A QUALIFIED TECHNICIAN A.S.A.P.. HOPE THIS HELPS. GOOD LUCK.

Go to advance auto or auto zone and have the do a trouble code read ( it is free).
The plug is located under the drivers side dash to the left of the brake pedal.
Press the esp off button on the dash and see if ithas an effect. on acceleration
Next I would try this it is expensive.
If it feels like it is bogged down when you first start to acceleratewill only creep about 10 to 20mph it may be the mass flow sensor located between the air filter and the throttle body. It has an electrical connection. Sand eats them up and it is a common item about $200.
