Computer problem
2004 Ford Explorer V8 All Wheel Drive Automatic 78200 miles

The first time it went into fail I was going 65 with cruise control on. Cruise went off and ABS light came on. A couple minutes later it went into fail mode with no change in engine performance. Than service engine light came on. I drove an additional 60 miles home. The next morning no warning lights, and drove a few miles and again fail mode. I checked the computer codes and got one code P2106, which indicated throttle actuator control system. I reset the computer and drove several days with no problems. I called two ford dealers and was told the in the fail safe mode the vehicle should have performance reduction. Yesterday while in a parking lot the fail mode once again appeared with no service engine light. Restarted engine and everything OK. Any ideas?

thanks
