Mercury Mystique

My first thought was that you may have a head gasket problem. To verify before spending much money, have a compression & leak down test performed on each cylinder. Each should read 90 to 110.

below the fog lights there is one on each side

the transmission is located on the driver's side of the engine and yes the engine has to be removed to change the transmission

You could change the spark plugs, sprak plug wires, computer chip.

Remove - battery cable Raise and support vehicle if needed Disconnect wiring at top of starter Remove starter mounting bolts Remove starter

my battery is new for mercery mistque 1999 but the light on the dash board goes on and off why

Means there is something wrong with your transmission. Need to hook up to a computer & get the code normally but can be external damage also. My 97 F150 did that when the transmission mount broke.

Replacing ERG Valves in a 1998 Mercury Mystique is fairly hard because it requires great precision to avoid blocking the EGR passage.

you need to get them down at 95 ft pounds

every other

What does the code P0190 mean on your 200 Mercury Mistique?

It is actually inside the transmission itself. You get to it be removing the transmission pan.

It sounds like the fluid pump is out, or almost out. Having to "re-start" the engine for it to shift right is definatly an electrical problum, and is very common on these transmissions. What you are doing is reseting the transmissions T C M,{or brain} it will shift right again, until it gets a code for a problem, then it wont shift right again.

It is probably going into "limp" mode which is a safety feature for these transmissions, which may seem aggravating, but is actually to your advantage.

It will get you to take the vehical to a shop to see whats wrong, before to much damage is done.

These transmissions are actually a great invention by Chrysler, and one of the best out there if rebuilt with all the up-dates and fixes they have made over the years.

Its truley an amazing transmission if you know what goes on inside. {all electrical}

It is very hard to diagnose without hooking it up to a computer for a complete anaylsis.

I would suggest you call around to a local trans shop and ask if they have "FREE" diagnoisis, most will do this free.

They will hook up a small computer to your transmission, and it will tell the tech EXACTLY WHAT ITS DOING INSIDE, AND WHAT FAULT CODES IT IS THROWING.

You can go from there on what to do.

"PLEASE NOTE"!!!!! MOST LARGE SHOPS ; IE "AMMCO" and the like, will IMMEDITALY TELL YOU THAT YOU NEED A REBUILD... GET A SECOND OPNION!!! FROM A SMALLER SHOP.

There may be other small things that you can do to make the "fix" on your trans.

Many times its just an "in-put" out-put sensor, or a solenoid pack, or the TCM its self. These items are WAY CHEAPER than a rebuild. That's why you need to see EXACTLY WHAT THE FAULT CODES ARE.

"DO NOT JUST TAKE THE TRANSMISSION SHOPS WORD THAT YOU NEED A REBUILD"

THATS HOW MANY SHOPS WORK.... PREYING ON PROPLE WHO DONT KNOW !!!!!!

{sad , but true} below is a "very informative site that list cheap "fixes" to your transmission. I found it very helpful!!!!!!!!!!!!!!!!!! look it over, clear down to the bottom of the page, it lists many fixes.

check by the pedals to the left if should be in the paneling there will be a little sticker pointing it out. you'll have to push it up if it has been engaged

It isn't under there, it is under the hood, next to the battery, where it says power distribution box

It is there indeed ya should notice it has a release on it that lets the fuse panel to drop down u may need a good flashlight for this. Take the access cover off an reach under the dash and release the clip system that lets it down. Easy easy easy

The passenger compartment fuse panel is located on the driver

Yes, a person can put oil down the dipstick shaft. However it is not advised to do so, because they cannot properly keep track of how much oil is being put in, and too much oil can damage the car.

This refers to the second oxygen sensor on Bank 1. Bank 1 is the same side of the engine that cylinder 1 is on, the very front cylinder on the drivers side. It could need to be replaced, or there could be a short to voltage on the O2 signal circuit, or it could also be that the connector has been corroded, and needs to just be cleaned. I believe this code is the same for all vehicles.

Different places on different vehicles.

According to the 1999 Mercury Mystique Owner Guide :

( 5W-30 ) certified for gasoline engines ( 2.0 and 2.5 liter )

exterior temp. sensor is located at the bottom in front of the radiator.If temp is way off or not showing you will need to replace sensor.

If you have a manual transmission, the shift knob should just unscrew off. If you have an automatic transmission, use a small (T5, I believe) Torx screwdriver and remove the small screw from the left-hand side of the shift knob, below the TCS button. Once that is removed, just carefully lift the knob straight up. The wires for the TCS button may be short, however, and you may need to clip them.
