hi,
if you are only feeling this in the steering when you stop, you more then likely have warped front brake rotors.
you can have them turned at a shop to get them straight again.
hope this helps, let me know if i can further assist you.
thanks,

650 rpm seems a bit low. should be around 800 to 850ish with ac off. at idel.
you may have a miss fire happening.
hard to say on this one with out actually seeing it. you may want to take this one in and have it checked out.
i will opt out. maybe someone else has some advise for you.
