Ok so I just went and bought a 1990 2 door sport 4x4, it's in great shape except for 2 things. 1 the rockers on both sides are rotted right out...and 2 the 4.0l(non HO) is once in a while idleing high for some reason...most of the time it runs around 900 rpm but it will somtimes when parked adjust itself to about 2000 and stay there untill it's shut off for a while. Magically back to 900ish....Any advise or tips on both issues would be GREAT! Pics will be comming soon!
