I just purchased a 02 hyundai accent and it sounds like it is skipping especially when it is sitting still.It also idles high.Could it be a timing issue?Or some kind of censer?Do I need to limit my driving until it is fixed?

Sounds like a misfire like a chugging sound maybe time for a tune up plugs and wires should be pretty easy if its a four cylinder right on top of the engine check the wires for charred discolored spots and the plugs for fouling(wet gunked up or burned away) but you should limit driving until its fixed to prevent further damage hope this helps good luck
