I have a 2003 G35 Coup, I took my car to get an oil and filter change...5 miles down the highway I passed someone while my RPMs were high and then my car died. While I was waiting for tow truck, I would turn key and car would turn on for 20 seconds, idle under 1000 RPMs and turn off. Mechanic told me my battery was dead. I replaced the batter and now the car takes a a few minutes to "get going" over 2000 RPMs and sputters and is "jumpy" while I am at a light (low RPMs). Mechanic believes I need a new "Throttle/Idle" part. Excuse my lack of "car terminology". Any help would be greatly appreciated!

Thanks!
