    Hi Dee, first i know this is a stupid question but are you getting codes that you haven't posted? next how many miles are on the car and is there a difference in the car in warm weather vs cold weather, or engine is warm vs cold?

SOURCE: Rough Idle 2000 ford Taurus OHV

This could be a bad a/c compressor or compressor pulley bearing.Try removing the serpentine belt and turning the compressor by itself.The bearing should turn very easily,and the compressor itself should turn.If it is vety hard to turn,it is bad.

SOURCE: my 2002 taurus dohc runs rough at idle, worse if i turn ac on!

The a/c makes it worse because you are asking the engine to pull a load missing one cylinder. If you have alternate transport or like working on a hot engine you can take number 3 wire to the autoparts and get one wire to match length. You may want 1 plug in case wire doesn't help.

SOURCE: what causes 2000 taurus engine rough idle but no codes

I had a head gasket going when I have a rough idle. Just weeping coolant past the number 1 cylinder. When I pulled the head the piston was all shiny and steam cleaned. $500 dollars all good now.

What does a P1506 error code on 03 Ford Taurus SEL mean


P1506 Idle Air Control Over Speed Error.
Vacuum leak or throttle sticking:
Are the vacuum controlled heater functions working properly?
Try plugging off the Evap Emissions hoses, large and small.
Use a tire gauge to measure idle fuel pressure, both with modulator valve normal and vacuum hose off. Should be 30 and 40 psi.Measure vacuum with a gauge. I would expect near 20 inches at normal idle.I'd replace the PCV valve, and carefully inspect the hose and connections.

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.

My 2000 taurus does not hold idle, even with engine at normal operatin temp. It started random and now is more frequent. Regards. G.


If it just dies, sounds like the Idle Air Control Valve. If it surges and runs rough, sounds like a vacuume leak, especially if it is the DOHC 3.0L engine, they have several vac hoses that go bad.

ISSUE: After a 1-4 hour engine soak time, long crank times and/or long crank to start followed by a stall may occur on some vehicles. No further stalling or rough idle will occur after the engine is running. The long crank and/or stall may be due to the Idle Air Control (IAC) Valve sticking.
ACTION: Replace the IAC Valve with a revised IAC Valve if no Diagnostic Trouble Codes (DTCs) are present. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
  1. Perform normal diagnostics and correct any DTCs as required by referring to the appropriate year Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual.
  2. If no codes are present, replace the IAC Valve by referring to the appropriate model/year Service Manual, Section 03-14. Refer to the following Idle Air Control Valve Application Chart for proper IAC usage.

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
