1996 Mercury Mystique - Answered Questions & Fixed issues

Your compression rings may be worn or dirty. On next oil change use a high mileage oil with an oil additive that will clean the rings.

Have you had the timing belt changed? It sounds like your timing is out of correlation. One tooth off is enough to cause a problem like this

Get an obd2 code reader or borrow one from a major auto shop and they'll help you out in retrieving it. You can get wireless ones that will transmit the codes to your phone. You can get them for as cheap as $5 with free shipping. ELM327 Bluetooth obd2 transmitters work best with Android and the wifi ones are better for iphones. Then you something like Dash Commander or Torque Lite to grab the codes and translate what's going on.

I take it it is the mercury or Town car in the Pic? Sounds like the shift valve in the transmission is gummed up or the "o" ring is damaged. The pan must come off the transmission and the valve or valve body needs cleaning. You local tyranny shop should be able to fix it with a tranny filter and oil change for around $300

Check the timing belt.

You'll need to add some detail here. All your question has for context is '1996 Mercury Mystique'. Adding washer fluid or lubing the door hinges is easy. A new head gasket isn't. There's a lot of ground in between. Folks in here can be much more helpful when you give as much detail as possible about the question or problem.

I hope helps with this...



Good luck (remember rated this help).

CHECK IF THE GROUND-WIRE IS PROPERLY CONNECTED

It's a transmission problem. Probably a bad TCC solenoid. Worst case is the valve body.

you have to have a funnel and you put it in the same place you check it at. You remove the dipstick and put the funnel in the hole and pour it in. You do have to keep checking it to make sure you are not putting in to much

Evap system purge control valve or circuit failure. Or vapor management valve concern

There is a censor for your temperature right on the engine block it is for your temperature gauge in dash gauges

The part broken is probably the blower motor resistor. Go online and look up this part by Year and Model. Sometimes besides the part, a photo of the location will be included in the article. This is a part that sometimes can be tapped with a broom handle or snowbrush and reactivated. Sad part of this is that it may work longer than any replacement part you would buy. Some had bad solder on components and would reconnect by tapping and arcing a new bond. So I really can't say that a new part would last better.

Check thermostat located on top radiator hose connected to engine. Good idea to change it and rule out.

Idle control valve stuck, on older vehicles the valve gums up with carbon, Its generally located near the inlet manifold, a cylinder about 15cm long and 5cm diameter and two or three wires, to signal the ECU. Remove and clean with carb cleaner.

have you checked the egr valve
