Ihad similar awhile back, not WOT but I did power out of a turn, car hicupped, check engine light came on, significant loss of power, poor idle etc. Pulled off into a parking lot, turned the car off, then back on, no change. Started to limp toward my dealer which was only a mile away and as I did it cleared up. Turned car off, then back on a second time, light was gone and the car has run normally ever since. This was propably two months and over 1000 miles ago. I figured it was some junk in an injector that caused a misfire but really don't know...
