96 metro nothing fix it

well here we go again,1996 metro 4 door automatic,4 cyl,the car will start fine and idle great,but if you hit the gas quick it wont rev up but if you hit the gas slowly it will rev up now if you turn the ac on it will get worst,i already replaced plugs, cable, rotor, cap, the injector fuel filter ,oil and also all the lifters cuz one of them was making noise and still does the same,the compression is 125 lbs each cyl it doesnt over heat and it doesnt burn oil all i can think of is maybe the auto transmission is bad i dont know anymore,with out the ac on you can get the car to run but only if you acelerate slowly all the gears in the transmission shift fine is only at take off,any help or ideas will be great ty

:banghead: If your compression is only 125psi in each cylinder, your engine is dead. Stock PSI on a metro is 185psi. Your car is probably generating 15hp. I would start looking into a new motor, or take it apart and rebuild yours.
