In a 1998 Mercury Villager, the mass air flow sensor is located in the air intake tube. The air intake tube goes from the air box to the intake.
The bulb end goes toward the engine.
The Mercury Villager does not have an interference engine (in spite of what you might hear) and will not be damaged if the belt breaks.
The copper pellet opposite the spring end goes into the engine.
Engine oil goes in the oil cap which is right on the front of the engine and has a picture of an oil can on it.
Amp module, get a new distributor, the parts inside are not serviceable.
my guess would be a catalytic converter going bad. you can remove the front oxygen sensor and drive it. if the problem goes away then it is probably the catalytic converter. nth njth ///////???????????????????kldghavnivaetahdsngahe
No picture, but all thermostats go with the spring side towards the motor. On thermostats I changed, there were words on them and stated which side goes up

The pellet, the copper part opposite the spring with the temperature on it, always goes "into" the engine. The spring end should face out.
It came from the factory with R12 (Freon). As R12 is so very expensive, I would convert this car to R134a. You can buy a conversion kit at most auto parts stores. If you have leak, make sure to have the leak repaired.
