I had the same issue when i slow down to a red light or what ever.. It would Idle rough, They said it could be many things but in the end, It was my CVT timer. Cylinder valve Timer is what it was called. After that it worked great and the check engine light went off. The part for that is about $75, Easy to install yourself.

I paid $1200 for that same repair in September 2012. A few weeks later the idiot light was back on. Took it back and they replaced the knock sensor again. Still not fixed; "CHECK ENGINE" light goes off and on frequently. Premium gas is not an answer either. I just live with it.
