1. • 1 Ensure that your battery cables are properly connected to the battery.
     
   • 2 Start your car.
     
   • 3 Let the car run for around half an hour. Most cars idle fast enough that the alternator will be able to charge a battery while sitting at idle.
     
   • 4 Turn off your engine and test your electrical systems. If they work properly, your battery has been charged. If they do not work, or are sporadic, turn your car back on and drive around for another half hour. After the drive, your car's battery should be sufficiently charged.

If you order it from the dealer, you will pay premium price for it. If you get if from a junk yard, you will probably have to strip, sand, primer and paint, but will be a lot cheaper.

Or you could talk to your local body shop and order through them.

There are few possibilities , that needs to be checked.If there is steady check engine light coming up on dash, then get the car scanned.At autozone service center its absolutely free to get car scanned,.Yes , they do car scanning for free.Once its scanned , it will give the error codes.So as per error codes , it will point out, what is causing the high idle problem.-----------
BUT in case if there is no steady check engine light coming up on dash, then then in that case the IAC valve ( idle air control valve) , EGR valve, vacuum leaks, low fuel pressure, dirty throttle body or MAF sensor( mass air flow) and TPS ( throttle position sensor).------- This are the possibilities that can cause high idle problem.----------- IN most of the cases its faulty MAF sensor, that causes this problem.So start with MAF sensorr cleaning and see if that makes any difference.Also test the MAF sensor and see if its getting voltage to its terminal.---------- Disconnect MA sensor and see if idle gets better without MAF sensor.IF it gets better, then replace the MAF sensor.-------- The sensor is located between the throttle body and the airbox.-------- But if MAF sensor replace or checked ok, then in that case.------------ Other mentioned possibilities needs to be checked, click this link below for more details:-------- http://technoanswers.blogspot.com/2011/09/1999-chevrolet-monte-carlo-idles-high.html -------------- This will help.Thanks.Helpmech.

a new what? not explained fully

THEN THE HEAD GASKET IS BAD IF LEAKING ABOVE THE WATER PUMP.

This is a common problem on GM vehicles. This link explains it and should help you out... http://vatspasslockpasskeysecurityhelp.yolasite.com/

Sounds like it might be your master cylinder that is bad.The seal around the piston inside the master cylinder is allowing fluid past it therefor letting the pedal go to the floor.

It should be in the fuse/relay box under the hood. You can also call the dealer and they will tell you over the phone if they are a reputable place.

Crank sensor.

UNFORTUNETLY YOU REMOVE THE DASH AND ITS LOCATED AGINST THE FIRE WALL
