Would it be a good thing to reflash the car with the same tune after o2 install? Car runs fine when i am driving around town but, when i get to a light the idle is a bit messy. Drops very low almost to an almost stall than it will go up to 1,000 or so. Its just all over the place i am just wondering if i should just reflash the tune.

Unhook the battery and pull the headlights switch for a few, then hook it back up. This will clear the adaptive memory
