58k miles. Just driving at about 40mph and those lights came on and the throttle wouldn't work, would just idle along. Tried turning it off and on a few times, no throttle response. Idled to a parking lot, turned it off and on, now it drives again. OBD reader said P060A Permanent Error, Google says "Internal Control Module Monitoring Processor Performance" or so. No other codes. So, after searching around, it could be anything. Any ideas on how to narrow it down without replacing things and hoping it will go away eventually when I've replaced enough stuff?
