Just bought an 02 WRX 4EAT about a month ago and I'm having some problems. The biggest one I need help with is when I'm driving at low speeds and rpms I won't move my foot from the gas and all of a sudden I will lose power. Then out of nowhere it will find power again. Hasn't happened yet when getting on the gas just at lower rpms. Any suggestions on what it could be? Also it has been having a rough and fluctuating idle as well. I don't know much about WRXs yet always wanted one now I finally got one, and I want it running right before I would do any mods. So any help is greatly appreciated.
Here's the info on the car if needed
2002 4eat Automatic Tranny 82k miles
