Mercury mystique throws out a huge amount of smoke and the engine idles what can it be ?

Smoke from an idling engine that shows when the engine is reved up indicates worn valve stem seals and worn valve guides. If the engine has some age on it then the stem seals are probably hard and cracked allowing the oil to be drawn into the combustion chamber past the valve stem. A skilled mechanic with the right equipment can replace the seals without removing the head so ask around for some one who does it on a regular basis.

How to recharge recharge airconditioner

Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle. Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power. Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can. Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood. Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care

My high side port valve is leaking how do i fix it ?

I am guessing you are talking about a/c. If so replaced the small valve inside the tube. It's almost like the valve core in you tire valve stem. Make sure you get the right part! If you use one from a tire, it will leak everything right back out.

A6 smokey on start up

If it's the org. engine it will has over 85,000 miles on it.
It's normal to has valve stem seal/oil seal on the head to leak oil into the cyclinder on high mileage engine.

The smoke you see is the motor oil drop from the valve stem seals. The oil drops land on the top of the cyclinders and it create black smoke at start up.

The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.

The correct fix is to wait until it's time for a head gasket replacement and let the professional CRC/service the head.

Complete head service is the only method to stop this internal oil drip problem.

Re-charge a/c in a 98 ford escort zx2

Your low side should have a "blue cap" on it. If it does not, it is located on the passenger side of the vehicle near the firewall.
