car is sluggish when you go to give it gas. I know that the catylitic converter is stoped up, and its using more gas than normal, do you know why.

Tom is right. the car is sluggish because the cat convertor is stopped up. The cause is because it is using more gas than normal. the reason it is using more gas than normal will take some work. the first thing i would do is look at the oxygen sensor. take it to autozone and have them pull codes. if you are lucky enough to only have an "oxygen sensor LEAN" code; you now know that your car's computer is compensating for a lean condition by increasing the fuel supply (increasing the injector pulse width). Why, now, is it lean? There could be vacuum leak(s); or there could be dirty/clogged injectors, or you could have a stopped up fuel filter, or you could have a bad oxy sensor. If you have not changed your fuelfilter do so now. Get a new cat convertor installed next. If the problem still exists look over the engine at all the small black pencil sized hoses for breaks/cracks/rubbed holes. Did not find any bad hoses? Still have fuel consumption problem? go to wally world and buy 3 bottles of chevron techron(tm) and pour all 3 bottles into your full fuel tank. This will blast any crud out of the injectors if they are not too far gone. This will take at least a full tank of fuel driving time to work if it is going to work. last, thing to do would be to replace the oxy sensor.
these are the only the most obvious things that might cause the car to use too much fuel. if these "first line" repairs don't work you may be in for some diagnostic time on such things as map,tps,ecm,further vac leak searching, etc.
be careful around the hot engine parts, and follow all directions on additives except the amount of techron to add to the system. 3 bottles at once is an old mechanics trick to quickly clean injectors on a car.
