Alright guys,

So after driving the car around the city for dinner, I haven't noticed any RPM fluctuations. Also, with the throttle body having been replaced, the clutch is so much better than it was. It's easier to shift and start out from a stop. I think this is definitely the fix....

Maybe recalibrate the gas pedal.
Turn on the key to RUN.
Slowly, fully depress and slowly release
the gas pedal a few times.
Turn off the stang then start her as normal.

I have an 07 with an Airaid CAI and have not
noticed any RPM fluctuations at idle.
I dont sit at the light with my clutch depressed.
Its always released and the tranny is in N.
Maybe they ironed the problem out for the 07s.....
