I have a 2002 chevy Cavalier w/ about 100,000 miles on it. Recently, the car pulls forward whenever I turn on the air conditioning. The tachometer jumps up and down. Also, when I start the car, the tachometer has been up very high (around the 2 mark). I feel like sometimes the car is on the verge of stalling (tachometer very low, almost zero) and the car pulls when going up hills. The car is still drivable, but I don't want to get in an accident. Does anyone know what's wrong with it? I can't afford to really screw up my car. Any help would be appreciated. I have no one to ask for car advice and I don't want to get screwed by a auto repair place. Thanks!

I am not sure i understand your question but here is what i think you are talking about. You said the car pulls when goin up hill i think you mean it pulls to the left or right if this is what you are talking about and the motor speeds up and slow-es down it sounds like to have a broke motor mount. That would cause it to pull and to speed up and slow down

Your Cavalier is equipped with a idle speed control motor which controls the idle speed, when you turn your a/c on you obc [on board computer] senses the extra load and readjusts the engine idle .. In cold conditions the fast Idle is caused by your car in full rich mode, sort of like when cars used to have automatic chokes on them,, are you getting a check engine light or a service engine soon light coming on,,if so it might have one of many sensors acting up !!!!!

You have given little to go on, But I think you need to have the throttle position sensor checked. Also, a bad O2 sensor could be at fault. If you take it to a GM Goodwrench center, they can hook it up to the diagnostic computer and figure it out quickly. If the car is in decent shape and doesn't burn oil or have any major leaks, I'd get it checked. The car is still relatively new.

Kinda of hard diagnosing a problem like yours by the description you gave, but sounds as if the idle control unit has gone bad. First, disconnect you battery overnight, this should reset the computer chip to the factory settings. If this doesn't cure the problem, than have the unit serviced by a qualified mechanic.
