Check the IAC, my friend had a 90 that did the exact same thing.
It may have also ran so rough that it plugged up the cat. I have seen cars that wont even run because of a plugged cat.
Check your fuel filter, you might not be getting tnough fuel.
Check the compression.
Check the gap on the plugs. Make sure that the plug wires arent arcing or shorting out anywhere. Check the cap and rotor (doesnt have coilpacks, does it?) for wear and gap.
Do the easy, cheap stuff first, then move on to the more expensive stuff.

plugged up cats only really result in lack of power. I have never seen one have symptoms such as what he explained. Also if the fuel filter was plugged it would not decrease system pressure enough for it to be the reason of his cocern, however if is only and within maintence schedule it would be a good idea to replace it. I agree with you though on checking smaller things first before making any assumptions.

I called partsource(just to hear there 2 cents) and the guy said change the distributor,cap and rotor, which i'm gonna do and the fuel filter and an oil change. But do you guys kno should i buy the distributor used or brand new?

ok a cap and rotor are parts of the distributor assembly and can be changed out as they are wearing items. The cap and rotor should be replaced with brand new iteams where if you were to buy a whole distributor assembly it can be expensive brand new so sourcing it used may be a better option. One way to check the cap and rotor is take it apart and inspect both items. They should conductors on the inside of the cap should be fairly clean and no pitting or corrosiveness and same goes for the rotor. These parts arc between each other and should be considered replacement just as much as spark plugs.
