    After a second warm start I have the same problem! These are all the solutions I have just surfed for to fix my 2000 Mustang 3.8.

    1. Replace EGR Valve.

    2. Check or replace Ignition Coil.

    3. ACT or ECT reading incorrectly.

    4. Clean MAF and Throttle Body.

    5. Replace IAC (Idle Air Controller)

    6. Replace Fuel Filter.

    7. Check DPFE Sensor.

    8. Replace O2 Sensors(both sides).

    9. Replace Spark Plug Wires.

    10. Check Temp Sensor - not the sensor for the gauge but the sensor for the computer.

How long have you had this problem? It could just be a bad tank of gas. Other things to check:
1. fuel pump and filter
Could be running on only 5 cylinders due to
2. spark plugs/wires
3. plugged fuel injector
Any problems with electrical? Like lights dimming at same time as running rough?
4. could be bad alternator putting excessive load on engine.

Idling is too slow at 500 rpm.......think about at least 650 rpm to charge the battery and keep up inertia for better take-off power.
Find out how to increase rpm,whether it's a screw-stop adjustment or a timing problem. don-ohio (:^)

2500 HD chevrolet low idle problem


Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

2001 mazda tribute v6 runs rough cold ildes at about 200 rpm till it warms up then its ok what could it be


I replaced the upper & lower manifold runners seals, now it runs perfect, The reason it runs ok when warm is because the manifolds expand and seal the gaps on the surfaces that the worn old seals are not closing. Also change the spark plugs.

Did you properly gap the plugs when you changed them? Improper spark will cause really rough idling at low RPM like that.
