At the right rear of the engine under the intake manifold and to the left of the oil filter. You will probably need to go under the car to spot it, it's the sensor with a three-wire connector arranged vertically. But you can take it out from above. It's held in with a single bolt with an eight MM head located just above the sensor. Un-clip and remove the electrical connector. Unscrew the bolt with a socket wrench & extension bar. Wiggle and pull the sensor out.
here is a picture.

I have the wiring diagram for this if you give me your email I will send you a picture of how to hook it up.

Have you checked the CV Axles? Since the noise goes away turning left to right. Another slim possibility may be the brake calipers but you said humming. And I would (assume- which means not always so) stuck calipers would only make the noise in one direction.

There is no stand alone TCM for your Cavalier. The transmission is controlled through the ECM. Sometimes faulty speed sensors can cause shift issues but on the TH125 trans most times it's transmission failure.

Good possibility that it has low fuel pressure due to worn pump or restricted fuel filter. Check these items. Also if the SES light is on, read the codes. It might tell you something about the problem. Watch this video https://www.youtube.com/watch?v=8PuIIWxJXAM

A flashing light usually means exhaust related

Tyhe first thing you shd always do on any car with starting problems is to check the spark on the plugs to localize the problem to either fuel or ignition problem. If u have an old spark plug lying around, remove one spark plug wire and attach it to the plug and lay it against the block. If it fires, when the engine turns, then it will most likely be fuel problem. If it turns out to be fuel problem, you can prove it by using starting fluid carefully into the breather area.

Could be eather be vacumm or timming a little off.

hi, check your trans fluid.. does it show on the stick? what is the color? red our dark..

That would be a heater tube. The bleeder is to remove air from the cooling system

I usually want to check sensor wiring circuits before replacing anything. As you can see, the map sensor shares ref voltage and ground with others. Orange wire with black tracer is signal return. The gray wire should be ref voltage 5 volts. The signal wire should be lite green. Vacuum for the map sensor is also important. What was actual trouble code was it two digit code or five?

Could also be a vacuum leak, which is why there's no change when you remove the vacuum line. Don't start replacing parts until you do some diagnostics

Hey Mizz_Kitty No, its not loose wiring (unless you or someone has been tinkering under the hood)..Do you have gas (are you SURE- add some to make sure - the gauge maybe WRONG!),,There are numerous things that could be wrong... TOO many to cover here.. I would recommend towing this vehicle to a qualified professional and let them diagnose the problem!!
