No park lights and rough idle ???
 

Well i was in a wreck about a month ago so i bought a parts jeep after i replaced the whole front clip, radiator, a/c condensor, power steering pump, belt i have no park lights and when I turn the headlighhts on the turn signal lights in the dash stay lit up and on top of that it will idle real rough for a minute the tach says its around 300-400 rpm and then it will rev up to about 1500 rpm by itself im thinkin this problem is a vacuum leak somewhere but im curious to hear yalls input.
