Welcome to the forum.

 

Which engine does your car have, petrol or diesel and engine size ? Does the engine run smoothly on tickover without stalling ?

 

Assuming your car is petrol, you could see if the MAP sensor on the inlet manifold is blocked with oil and check if the air filter is clean. Also check if the throttle body and plate are clean inside (I think you have already done this).

 

If you have an accelerator pedal with a cable, then the cable may need adjusting to remove any free play at the throttle body end. From the Haynes manual this is done with the throttle cam against its stop, pull the cable out of its grommet to remove any free play and then refit its clip to the outer cable in the last exposed groove in front of the grommet.
