RE: Idle fluctuation,surging, erratic
its your IACV, my car did the same thing. It's located on the back of your intake manifold and theirs 2 bolts, take them off and 2 hoses take them off then near the bottom theirs 3 phillip screws to unscrew, and a clip and take that off and it will come off. Then you can clean it w/carb cleaner and put it back on or replace it. It's also good to check for vaccum leaks and break booster.
