2002 LS parking problem?

Anyone heard of a problem with a Lincoln LS where the engine races while parking the car and leaving 12" skids marks? Assume the obvious has already been ruled out...the driver did not have a foot or any part of foot on gas pedal - only on the brake - this has happened 3 times. We are looking for answers as the dealership is coming up empty. Otherwise, love the car!

New to me. Scary, though.

propably is running rich, check your ecu for a/f if you are stopped and it is running rich on the first time you give it a bit of gas or it gets in some air it explodes, by doing it.
Happened to me but my ecu is fucked so i can't complain
