The distributor cap, mentioned by Roody, is the thing that all the sparkplug wired go to on the back of the engine.
A new cap and the rotor underneath it costs abour $15.00 US or approximately three McDonalds' Happy Meals
The toughest part is keeping track of which spark plug wire goes where, so carefully remove a wire then place it on the same connector on the new distributor cap.
Also, use the following web page to thoroughly check that all your vacuum hoses are hooked up correctly:

If any lines are loose or crumbly use the above page to replace those lines. The best way to replace them is to take one to your local auto parts store and buy about 3 feet (1 meter) of the same-sized stuff then cut and replace them all!
That should, at least, eliminate vacuum leaks as a cause of bad accelleration.
Unfortunately, The 1.3 isn't the most powerful engine around. A 10-20 year-old engine that hasn't been rebuilt - doubly so.
I hope that this helps!
