this taurus is running a little rough at low rpms but runs fine when you get 20 on 2003 Ford Taurus

the engine idles rough in drive. put the shifter in park and it runs smoother.I changed the plugs, still runs the same. should I change the plug wires too. (110000 miles on plug wires)

Vacuum leaks are fairly common on this engine. Check pcv system.

Ok! Feel of the hoses, may look ok but are 'mushy' and will collasp then leak with vacuum applied. All vacuum related hoses! Look closely, some are hidden pretty good.
