If this is a general noise, it could be the transaxle. When you are accelerating, the engine is pushing the gears, and when you let go of the pedal, the vehicle starts to shift back down. If this is an engine noise, it could be predetonation or a valve problem.
On the brake pedal.
On the brake pedal assembly.
Stop light switches are mounted on the brake pedal lever, typically.
The 1995 Mercury Villager turn signal relay switch is located beneath the drivers side dashboard. The turn signal relay switch will be left of the brake pedal.
This is usually cause by a stuck brake light switch on the brake pedal. Replace it.
It would help to specify the type of noise and type of vehicle in question.

A 1997 Villager has a red button behind the driver side kick panel next to parking brake pedal. I found it by going to Ford.com/parts down loaded the owners manual. If you don't have the owners manual thy this.
a "knocking" noise could be your lifters. and the ticking when accelerating and letting out of the gas is the same thing. check your oil and if it's full then you may need to think about either having them adjusted, or getting new ones. depending on what you have depends on whether or not you wanna sell it
