First, make sure you have a working thermostat. Check the temperature sensor, manifold air temp sender, throttle position sensor and possibly the MAP sensor. Also test the fuel pressure regulator. These items work in conjunction with each other to regulate fuel and most likely you will find a problem with one or more. Tests are outlined in most inexpensive manuals such as chilton or haynes, which will help you with future problems as well.
good luck

its most likely your bearings could be water pump /alt/ idler pulley/ adjuster sometimes i will spray w-d 40 or liquid wrench rite at the inside of the pulley i think its coming from and when it goes away i know which is bad also you can use a sounding rod , a short plastic or copper tube ,even a broom stick to hold to your ear and narrow down the problem.A mechanics stethoscope is the best.

double posted, minus the key verb. how.

a hole in the top of the piston calls for either a different engine or total rebuild of the one you have.. how do you know its a hole in the piston?? has this been checked by someone who knows what they are looking at??it may be head gaskets.. that is a upper engine rebuild..still a job..is the car worth it??

Check the horn itself by running a wire from the positive lead of the battery to the connection spade on the horn. If it works, you may have a bad horn relay or the problem may be in the steering column.
If you have air bags, DO NOT attempt to work on the column unless you exactly follow directions for that found in either haynes or chilton manuals. Otherwise, your air bag may deploy and hurt you.
If the air bag light on the dash is on, chances are that the "clock spring" in the column has failed.
