The map sensor measures vacuum in the intake manifold, so a faulty sensor would not make a noise. The engine would run lean or rich and the check engine light would be on.
A squealing engine is usually a problem with the serpentine belt or one of the accessories the belt drives.

This sounds like it could be related to a bad TPS. When you have a bad Throttle Position Sensor, it can put too much fuel into the system causing all sensors down the line to be clogged. The MAP sensor you replaced may already be bad again.

When i turn on my heat my 2004 trailblazer stalls

if this happens while the defrost of ac is turned on, it could be a seized ac compressor which will cause the serpentine belt to squeal and drag making the engine sometimes stall. if it happens with the ac off and the selector on say the floor, or dash vents, the issue could be a bad alternator and battery. this is confirmed when the blower motor engages and the lights dim and then the truck goes dead.

computer said Map sensor and Cooling temp sensor I replaced Map Sensor and Cooling temp sensor will be done tomorrow . No DTC - diagnostic trouble code say's to replace a part , with each factory DTC a diagnostic flow chart or trouble shooting chart is supplied . Checking the electrical circuit , computer etc... before any parts are replaced . From your post i would say your best bet would be to take your vehicle to a qualified repair shop .

Map sensor bad and can't find one

A manifold absolute pressure sensor (MAP) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). This is necessary to calculate air density and determine the engine's air mass flow rate, which in turn is used to calculate the appropriate fuel flow. (See stoichiometry.)
An engine control system that uses manifold absolute pressure to calculate air mass uses the speed-density method. Engine speed (RPM) and air temperature are also necessary to complete the speed-density calculation. Not all fuel-injected engines use a MAP sensor to infer mass air flow; some use a MAF (mass air flow) sensor. Several makes use the MAP sensor in OBD II applications to test the EGR valve for functionality. Most notably General Motors uses this approach.

2005 jeep liberty diesel code # p0101 map- sensor out of range what is map

The MAP sensor (MANIFOLD ABSOLUTE PRESSURE) changes voltage or frequency as intake manifold pressure changes (air flow increases or decreases). The engine's computer uses the reading to advance or ****** engine timing. On older, non-fuel injected engines the vacuum advance on the distributor did basically the same thing.
The MAP sensor also works with other sensors on the Jeep engine, specifically the Throttle Position Sensor (on the throttle body) and Crank Position Sensor (on the transmission bell housing) to control other fuel flow and ignition timing functions.
If you're having problems with the MAP sensor, or are getting a Check Engine light and code for the MAP sensor keep in mind that other problems may cause that error code.
Bad vacuum hoses, vacuum leaks, bad EGR valves, intake manifold leaks, clogged air filter can all affect the MAP. sensor. To know for sure all the other sensors should be checked for correct voltage and perimeters
Also, if you have done any mods to the engine, especially intake, exhaust and ignition mods you may get an error code for the MAP or incorrect reading and a resulting loss in power or increased fuel usage.
The map sensor is easy to change with a couple screws off the Throttle body.. The part the air inters (the air breather). Buy one from the auto parts store if your sure that is the problem and just replace it..There is no adjustments to it...

It really sounds to me that you have a small vacuum leak in a line somewhere.You can try spraying the motor vacuum lines with soapy water with the vehicle running to find a leak. Also listen and feel under the dash for leaks and hissing sounds.
Hope this helps.......
