Sometimes a high idle can be caused by the oxygen sensor being faulty. These are available cheap on E bay @ CBS automotive. I have a contour which had the same problem. I got two sensors for under $60.00 and have had no problems as of now...Hope this helps.

SOURCE: 2006 ford taurus sel ++ rough idle

If the check engine light is on, take the car to an autoparts store and have them scan the computer for any faulty codes that it has stored. Most parts stores will do the scan for free. It sounds like a faulty idle air control valve, but getting the codes will identify what faults the computer has noted and in what systems. Hope this helped and best wishes.

SOURCE: 2003 ford taurus idle problems had trouble codes

A code P0174 may mean that one or more of the following has happened:

  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure

SOURCE: why does my 2000 ford taurus idle so high when i

That is just the way the engine warms itself up to operating temp and gets the oil and fluids moving around to lubricate the engine.

Why does my ford taurus idle high code P1506


The code is for the idle air control valve which controls idle speed.
The problem could be a faulty control valve, or a vac leak which is letting in air to the intake and bypassing the control valve.

I have 1990 ford f150 5.8 liter it idles high when in park and idles about 1200 rpm when in gear and sometimes surges up and down. i have clean the idle control and check showing 12.5 ohms still won&#


One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

I smell gas a little in my 1990 ford taurus any idea where to start looking???


First, take a quick sniff of the exhaust when the engine is idling. If you smell gas there, check your spark plugs and wires to eliminate misfires, then check for leaky fuel injectors (leaking excess fuel into a cylinder).

If the exhaust smells normal, you'll need to inspect the fuel delivery system. The most probable place for a leak would be the fuel lines under the car; it's old enough that a line could be rusted through and have a pinhole leak somewhere. If you suspect a spot but want to verify it by turning on the engine to pressurize the line, be sure to wear safety goggles. You don't want gasoline sprayed in your eyes.

Why does my 2000 ford taurus idle so high when i start it


this is normal, if the idle wasn't high (about 2,500 RPM) the engine wopuld stall out until it warms up to normal temperature. If it is above 3000 RPM for more than a few seconds you have a problem.
