hello guys i have a 96 1.3 automatic 4 door metro,the problems is the following,the car starts perfect idles perfect BUT..... when you put the car on drive and you press on the gas pedal it will move very slowly kind of like when you let go on the brake and it moves only with the idle you will have to push the gas pedal very slowly to get the rpms going and if you put the ac and then it will get worst any info will be great ps you can hold the pedal all the way to the floor and it will do nothing just move very slowly and if you let go on the gas quickly it will stall out.

Sounds like bad injection problem. When was the last time you paid for a whole injection cleanning? If your answer is more than six months or 25000 miles, you better check it before any aditional troubleshooting. Also you may be interested at the same time in a whole tune up (rotor, rotor cap, sparks & wires, gas&air filters) amnn.. not sure if I am overriding anything.

Hope this helps,

Ninja:
Sounds like this is the same post you did before. Please check and erase one to concentrate on the one you left. If you say your car is RPMing (what a verb!) fine then should be a problem with the tranx. Is it automatic? If not, maybe it is time to check the clutch: take it to a hill (going up) stop the car in the middle of the hill and try to start over there. If your car just accelerates normally but no moves, your clutch needs to be replaced. If it doesn't accelerates at all I have no idea how could it be RMPing has no sense. Please, remember to erase one of your posts.

I would definately do the injection cleaning, and a tuneup first. Does it feel like hesitation in the engine? Or like something is stuck? Sounds like maybe one cylinder isn't firing. Could be a bad spark plug, or wire, or a bad cap and rotor.

there isn't hesitation all cylinders fired up fine i replaced fuel filter plugs and so on i havent clean or change the injector yet but as i said before,lets said you are on park,press the gas pedal and you can hear the air been suck in by the engine,but it wont increase the rpm only if you press the gas pedal very slowly you can get the car to increase rpm and if you put the ac wont even rev up doing it slowly,i pull one of the new spark plug and is cover with black carbon like is runnig very rich honestly i dont have any idea i guess will do the injector

Sounds to me like a faulty Throttle Postition Sensor. Get a Haynes or Chilton's manual, and an OHM meter, and follow the instructions n how to test it.
