I have a 07 GT fitted with a Paxton Non-IC supercharger and a few other mods. The car has about 25,000 miles on it and was dyno tuned locally in Hawaii.
Recently, I've run into a strange occurance when starting the engine. Every now and again, the car starts but begins to stumble while idling. Sounds like it is going to stall but it doesn't. It takes a couple minutes for it to get on it's feet and the idle returns to normal. During the stumbling, if you gas it, it will stall. This problem is very much intermitent, and only occurs about twice a week (no big deal I guess because the car is a daily driver). Still, it's enough to drive me crazy knowing something ain't quite right. I'm not sure where to start on the diagnosis. The car has not thrown code yet either. Any help would be appreciated.
