Any number of things. To find out scan for the OBDii trouble codes. Any auto part store can do it for free. My guess would be a misfire or a vacuum leak.

Tune up or a bad vaccum line ! I just fixed my 1999 Taurus se last night and it was a vacuum hose but it also needed a tune up so I did that also and now iui t runs perfectly ..
