SOURCE: Electronic Throttle Control light

I took my 2004 Dodge Ram 1500 5.7L Hemi to a mechanic that works from a garage at his home, recommended by a friend of mine. He removed and cleaned the throttle body and sensor(s?), then reinstalled them, and then disconnected both battery cables and held them together for 2 minutes so that the engine controller could reboot with the factory default settings, then reconnected them. I had bought a can of throttle body cleaner on my way over to his house for about $3.00. He charged me $40.00 for the job. This was done mid-February, about 10 weeks and 2500 miles ago. So far, the problem Has Not happened again, the truck has been running great!

SOURCE: 2006 mercury mountaineer interior lights will not shut off

There is some problem with the door switch(s) which should turn the lights off when the door is closed. Look closely at the switch and make sure that the proper contact is being made within the switch. There could be corrosion.

SOURCE: Where is the throttle position sensor located on a

Remove your air intake hose at throttle body opening. Look at plate across front of the opening, the shaft in the center that it is attached to, will have your TP sensor on the end of it, at the outside of the housing. This may help. (picture)7fc7240.jpg

SOURCE: I want 2 change 2004 mercury mountaineer transmission fluid

The best way to change it is to flush it out You can do it yourself, but I do not recommend. A shop that is good like a Monro or Firestone usually charges about 100 bucks to flush and that includes the fluid. If you do it yourself, you will save about 60 dollars, but you risk damage to your radiator.

you will need a hose and an adapter. you back out the lower, or upper cooler line for your trans, whichever is the easiest to get to, (Some trucks have an auxiliary engine oil cooler, but make sure you are flushing the trans lines) put the adapter into the rad where you removed the line, and put a hose from each one down into a bucket. Have about 14 qt's of ford trans fluid ready. Put the funnel into the trans dip stick, and start the engine. pour the qts into the dipstick tube while the old fluid is pumped into the bucket. When you have about two gallons pumped into the bucket shut the engine off and reattach the line into the radiator. start up the engine and check your level. Fill with additional fluid if needed.

note: some say you should drop the pan. two things, you only change half the fluid when you do it that way, and second if you need to change the filter because it is clogged, it is too late for the transmission. The filter is only there to protect the valve body, not keep the fluid clean.

Hope this helps

SOURCE: 2003 mercury mountainer, wont start,

If this truck is spinning over but not starting then its going to be due to a lack of fuel or spark, the first thing would be to scan the computer, the computer will store a code when something is not operating correctly, for example lets say the crank sensor went bad and truck wont start, the computer will know and store a code for the crank sensor, its always good to scan first, but the problem is a scan tool is needed or you would need to go to an auto part store but truck wont run. you will need to do some checking,i would almost bet its a fuel problem, the first step would be to spray starting fluid into the throtlebody and see if it starts, it will shut back off when fluid is burned but will tell you its a fuel problem if it runs, and if that doesnt work then remove a sparkplug wire and place it near the engine and see if it sparks, if you can get to coil remove wire from the coil and see if it sparks, this will tell you if its getting spark. you will need to do this tests and let me know the results and get back to me and i will let you know where to go from there. good day, Note. a qood tip , try to beat on the bottom of the fuel tank with a rubber hammer while someone is trying to start it and see if it starts, try this first and see, what your doing is shaking the fuelpump and this sometimes makes it run due to a dead spot in the pump electrical components, if it starts then the pump is bad. let me know the result. good day.

2005 mercury mountaineer pressed brakes vehicle accelerated instead and crashed. What could have happened?

Could have had a bad signal to the PCM - engine computer . Your vehicle has electronic throttle control . Look under the dash at the top of the gas pedal ,you'll see wires going into it . Has a DC electric motor that opens an closes the throttle . Giving the vehicle more or less gas . This is controlled by the computer from inputs from the APP position sensors an suppose to be checked by throttle position sensors . Computer problem or wiring etc.... Take it to a Mercury dealer and have it checked .

Check engine lite 2002 mercury mountaineer

Did you do a complete OBD code-clear of the computer?
Codes don't reset just because you fix the problem. Many of the codes need to be cleared using a OBD machine - buy it at Auto repair places for about $60. You also have to disconnect the battery for a minute to reset some of the codes.
If the codes don't come back, you are good. If they reset again, you still have a problem.

2000 Mercury Mountaineer 5.0L engine. idle speed speeds up and slows down. Idles too fast.

dirty or bad idle air control valve i would at worst the egr valve but most likely the idle air control valve which controls the air and idle from the throttle body try taking it out and cleaning the tip as well as in the throttle body where the control valve goes in if that dosent work replace it and the check engine light does not have to be on for it to be bad.good luck to you.
