Yes, I forgot to mention, the tires had nitrogen in them, but I removed that and replaced it with air and made sure all the tires had the exact same recommended tire pressure (40psi in this case) and that did not help. I had a shop check the all the front end components (yesterday), although I am not sure if they checked the camber, toe and caster. But anyways, they could not find anything. They said that they "think" its the aftermarket rims and tires (even though I explained to them that it was doing it with the stock wheels and tires). Also they said that they "think" also that it could be the aftermarket crossed-drilled and slotted rotors I have on there (even though they meet OEM spec, and do not cause any vibration upon braking). Needless to say, they did not help me much other than to tell me they are not sure what is causing the vibration. I have an appointment today to with a different, more reputable shop, that has a "on the car tire balance system" or something like that. When I called the shop to make the appointment for today, the guy said that he has never met a vibration problem that he could not fix. So hopefully he hasn't met his match his with my car.
Also, on a side note: I should have added the fuel stabilizer upon storing the car, because for about three weeks after I got it out of storage it was hiccuping and burping and even stalled a few times at idle, but after a few weeks, and then on after, it runs great.
