p0302 code, cylinder 2 misfiring,run rough, cleaned IAC, AND TB,worked ok 2 mile

What is your question?

it worked perfect for 2 miles the i stoped at the store, then it was back to rough after i stopped the car, i feel like i was suppose to drive more so the car readjust to the clean IAC? anyone experience that? i have to cancel anything that will not make it work so good, what is that, i guess i will try to clean it again..and try again
