Rough idle
I have a 13 gt track pack. When the engine is at optimal operating temperature, when idling the revs are fluctuating between 600-800 rpm. Is this normal or a vacuum leak?

is the motor sputtering? Like it's not timed right? Or are the RPMS just changing like there's a control issue?
If sputtering, I don't know. I the RPMS are just changing, then that's a computer issue most likely. Pull the battery cables for a few minutes, re-attach, start-up. See what happens. It's just a basic step you can do on your own. It may or may not help.

How many miles? Some say this happens when throttle body and/or MAF needs cleaning.
You didn't provide much info.
How do you drive it - in traffic all the time, all highway, mix of both? Baby it all the time so it loads up? Or do you take it up to redline on a regular basis and blow the crap out of it?

I will disconnect the battery.
The motor is not sputtering, it is fluctuating rpms.
Its has 36500 miles.
It is driven mixed 50/50 city/hwy.
I am gentle on the car and rarely drive agressively.

If the fuel filter replaceable? If so, I'd start there and also clean the MAF sensor.

It is fluctuating because the computer is constantly having to adjust the air/fuel mixture to keep it running. Which usually means it is constantly not getting enough of one or the other. so it fluctuates as it adjusts.
