Mine was doing that, I have a 2006 GT.
I had to replace the Alternator to get ride of the surge while driving and cleaned the IAC really well for the surges to stop while at idle.

Note:
I was getting the Cam alignment error due to a faulty diode on my Alternator.
A few shops said if the Alternator is going bad it will produce surges at idle and while driving.
Dame thing cost 300.00 smackers for a rebuilt one with lifetime warranty.
Funny thing is the only place I could find one fast was Pep Boys.

That badly sucks when the car is bugging down but does not give the right codes for diagnostics. Hopefully you may come up with the technical solution for that matter coz you can't just completely rely on the electronics of the car.
