2007 FORD CROWN VICTORIA Engine Problems

My 2007 Crown Victoria has had a worsening unintended acceleration issue over the past year. When hitting hard bumps the car will suddenly begin revving my itself (normal RPM is 600 idling in drive and 800 idling in neutral) when this issue occurs it will sit around 1k rpm in drive (pushing against the brakes so I must hold them down very hard) and will shoot up to 2k rpm in neutral. when the issue is occurring it drives the car forward with no user input. this issue has been becoming more and more frequent with it happening up to 5 times in a 15 minute drive. It is very unsafe and has caused me to hit a parking pole before as I could not slow the car down fully.

THE HEAT SHIELD COVERING THE LEFT SIDE ENGINE EXHAUST MANIFOLD HAD CORRODED AROUND THE ATTACHING BOLTS ALLOWING THE SHIELD TO FALL AGAINST THE STEERING SHAFT. I REMOVED THE SHIELD BEFORE IT COULD INTERFERE WITH THE STEERING FUNCTION. *TR

WHILE DRIVING THE VEHICLE AT HIGHWAY SPEEDS (60-70MPH) GOING UPHILL, WHILE MAKING A SHARP TURN LEFT OR WHILE ROCKING THE STEERING WHEEL TO MAKE THE REAR OF THE CAR SWAY SLIGHTLY TO THE LEFT, THERE IS A SURGE AND COMPLETE LOSS OF POWER FOR 1/2 SECOND. THIS CAUSES A SURGE/JOLT FEELING IN THE VEHICLE LIKE THE VEHICLE TRANSMISSION OR ENGINE HAS LOST ALL POWER. IF YOU TRY TO SWAY THE VEHICLE IMMEDIATELY A 2ND TIME NOTHING HAPPENS. IF YOU WAIT SEVERAL MINUTES AND SWAY THE REAR END AGAIN THERE IS AGAIN A HEAVY SURGE AND LOSS OF POWER. I ALSO OBSERVED THE TAC-OMETER SHOW A LOSS OF POWER FOR A BRIEF MOMENT. IF YOU ARE GOING UP HILL AT HIGHWAY SPEEDS AND THE VEHICLE SWAYS TO THE RIGHT OR YOU SWERVE THE STEERING WHEEL TO MAKE THE VEHICLE SWERVE TO THE RIGHT (BODY ROCK TO THE RIGHT) NOTHING WILL EVER...

THE OPERATOR OF THE VEHICLE APPLIED THE BRAKE TO STOP AT TRAFFIC LIGHT ENGINE STARTED TO REV AND ACCELERATE ON ITS OWN AND MOVE FORWARD. *TR

LEAKING INTAKE MANIFOLD AT THE COOLANT CROSSOVER (THERMOSTAT HOUSING). ALUMINUM CROSSOVER BECOMES SEPARATED FROM THE PLASTIC INTAKE MANIFOLD WHICH WILL CAUSE OVERHEATING AND SEVERE ENGINE DAMAGE AT ALL SPEEDS. THE ENTIRE INTAKE MANIFOLD WILL HAVE TO BE REPLACED IF THIS CONDITION OCCURS. *TR

THE OPERATOR OF THE VEHICLE APPLIED THE BRAKE AND STOPPED THE VEHICLE, HOWEVER, IT STARTED TO ACCELERATE ON ITS OWN AND MOVE FORWARD. THE ENGINE CONTINUED TO REV AND THE VEHICLE CONTINUED TO MOVE FORWARD TO THE POINT THAT THE OPERATOR HAD TO PLACE TWO FEET ON THE BRAKE. THERE HAVE BEEN SEVERAL OTHER COMPLAINTS OF THIS NATURE REGARDING CROWN VICTORIAS. THIS VEHICLE IS A 2007 FORD CROWN VICTORIA POLICE VEHICLE. *TR
