Is the idle air valve an acceleration problem? It started accelerating it self now that its getting colder. Is it like the choke in older models?

No to both questions. The idle valve is only for idle control, letting in more or less air as idle conditions warrant, to keep engine at proper idle RPM. The old choke would reduce air supply on a cold engine to allow starting with a richer gas mixture. That function is taken over by the computer in injected cars by allowing longer injector pulses to give richer mixtures in cold engines. Once warm, the 02 sensor controls fuel trim through the computer.
By "accelerating itself", do you mean your idle is higher now that it's colder outside? I suppose it's possible if the idle valve is out of calibration, it might cause that. It is computer controlled, so proper diagnosis of the idle control valve requires a multimeter. The throttle position sensor should also be looked at for a high idle. Good luck.

Bucking, slow acceleration, & shuts off

it can be couple of thing Try a fuel injector cleaner or new fuel can be vacuum leak. Engines need a vacuum to run especially at idle which is when your car dies. It could be a stuck EGR.
If the check engine light comes on it will store a code so take it to a shop and pay them to read the codes. This may give you a starting point.
