Amp module, get a new distributor, the parts inside are not serviceable.
This is not possible on a modern vehicle like the Villager.
I would start by purchasing a repair manual.
The car doesn't run right, that's what happens.
To disable the factory alarm on a 2000 Mercury Villager, put the key in the ignition and turn it halfway. Let it stay in the spot for 10 minutes and start the car.
There is no power steering in a Mercury Villager at start up in cold weather due to a failing pump or low fluid. Fluid becomes much thicker in cold weather and is much harder to pump.
Tires perhaps? My 95 Villager would start vibrating right around 70 mph. When I replaced my rear tires the problem went away. The tire tech said that one of the belts had snapped in the tire. It runs great now.
You don't. The ignition is required to start the car. If it fails you need a new ignition switch.
It is possible that the 1997 Mercury Villager simply needs a tune up. New spark plugs and wires may make a great difference.
Have your cat converter checked out.
NO Emission control only, does not affect performance.
Dead battery? Battery cables in need of cleaning or replacement?
I had this problem and it was my battery,but could also be in need of antifreeze.
