Intake manifold is subject to extremely high temperatures. ford's current design includes a plastic intake manifold that is susceptible to warping and may cause engine failure if coolant looses pressure due to leak. *tt
This is another of an on going acceleration issue when depressing the foot brake. in this instance i had just backed out of a parking space in a shopping center and drove maybe 200' and had just about rolled to a stop sign for ga highway 212 and very slightly depressed the brake pedal to come to a complete stop. as soon as i started pressing the brake pedal, the engine picked up rpm and i immediately moved foot from brake pedal. end of acceleration. by this time vehicle had already rolled to a complete stop. i did not, as ford seems to think, have my foot on both the gas and brake. the very light pressure i had applied would have my foot three to four inches away from the top of the gas pedal. yes, i had my foot on the brake. i had to remove my foot from the gas to get to the brake. this is a vehicle malfunction. not operator error. i am unable to determine a failed component.....fuel? brake? electrical? i don't have a clue.
