My car would almost die or idle really rough when I came to a stop, but not all the time. It would do it always if I sped up and then had to come to a sudden stop. Driving at a normal speed on the highway it kind of hesitates like I was driving into a strong wind.

Since then I've replaced both O2s and the coil.

The car idles much better now when coming to a stop but it seems like it still wants to idle rough, it's also better on the highway but still hesitates just not as much. It has all the same symptoms, just all much better since replacing O2s and coil.

It runs perfect when cold. Plugs and wires seem fine, what else should I check? Is my opti on the way out?
