Hi, The squeal should be basic enough, that will be an issue with the belt either its tension or physical condition. If it has any cracks at all on the ribbed side it will need replacement. If you can flip the longest section of belt more than 90 degrees easily between your fingers, it needs to be tightened. If the tension is proper and the condition is good, then your compressor may be locking up (causing the belt to slip). This is pretty rare though, it is usually belt related.As far as your drivability issues go...When you press the gas pedal does the engine rev but not propel the vehicle forward, or does it bog down and not rev properly either?

it sometimes does nothing when pressing the pedal! or it will hesitate to go unless i keep mashing the pedal repetedly and then i get burst of power to mover the car i have to drive about 2-3 mins sputtering and hesitating untill it seems like to car stops and acts kinda normal again for the day ..until it sits again to extened time then the same.....and always the slow laggy acceration and jerky hard shifting from 1st to 2nd/3rd gear .... sometimes !

Thanks.With regard to the hesitation and no response from the pedal, can you check and see that the linkage on the throttle body is moving properly/smoothly when the pedal is applied?

and u tell me where exactly that is and how?
Expert:  Doug replied 5 months ago.
Under the hood locate the big plastic intake duct connecting the air filter box to the engine. On the engine end you will see a cable attached to a rotating assembly on the side of the throttle body. When you press the gas pedal you will see this rotating assembly turn as a result of the cable movement. Make sure this is smooth and does not stick.

ok i will check ....also when i bought the car they said the caddilac converter need to be cleaned or replaced
Expert:  Doug replied 5 months ago.
That's going to be our third suspect.Check the cable operation first to make sure everything is smooth as that is one you can do on your own. If it is not operating smoothly then we would be dealing with either a pedal or throttle body issue (replacement in the case of the cable, cleaning or replacement in case of the throttle body).If the cable operation is smooth then our second and most likely culprit will be the throttle position sensor. This is the sensor on the side of the throttle body that reads that rotation. if this sensor goes bad it will cause random no response from the gas pedal, low idle speed/running rich, and significant shifting related issues.To check it requires a scan tool.... and even if you wanted to just roll the dice and replace it you still need a scan tool (not a code reader) to calibrate it, so a trip to a shop will be in order regardless.If the throttle sensor is reading perfectly correct, all linear smooth movement and properly calibrated, then and only then would we start looking at fuel/exhaust issues (low pressure, clogged catalytic converter, etc). These are not primary suspects at this point due to you having shifting issues too which when we look at single items that could cause all of your issues we really are only concerned with the cable/throttle linkage moving smoothly and the throttle position sensor.
