An idle control valve is nothing but an electical motor. Electrical motors will build up corrosion on the windings inside of them over time and will fail. Cleaning the carbon buildup off of the valve itself and the idle ports will only fix your problem if that is the problem. If you inspect it and there isn't chunky carbon to hold the valve open chances are you need to just replace the valve. However if you are just having and all around idle problem all the time check for a vacuum leak before you start getting into replacing components.

sounds like you have a very dirty mass air flow meter. invest in a new one and be sure to clean the throttle body with an appropriate cleaner and tooth brush.

Check your vacuum controllers and injectors if equipped. It sounds like your vacuum is falling off when the engine reaches operating temperature which points towards a bad MAP sensor/valve or a bad PCV valve.

1997 ford escort idles rough when hot


1997 escort idles rough, the first thing is to make sure the throtlebody plate is clean. This sounds like the idle may be staying to low at times if it smooths out with ac on, when the ac is turnned on the computer raises the idle a touch to make up for the strain on the engine from the ac compressor, clean throtlebody and look at and clean idle air control valve, if this valve is not controlling the idle when needed the engine will idle lower than normal and cause a rough idle.
Another thing is the sparkplug wires, take a look at those, if at night or with a good eye use a spray bottle and spray a mist over the wires and watch for any sparking, this spark may be very small so look at each wire closely or may be big enough to see and hear. this is where i would start. good day.

Truck shuts down when it goes to idle


Hi.

Check idle air control system. The system comprises a valve that allow extra air into the engine when the engine is idle. If the valve is stuck, if there is a problem with IAC wiring or solenoid or if the vacuum hose connected to the IAC has a leak you get engine running rough and turning off when idle.

Check air intake and sensor (MAF and AIT). Replace air filter. Air intake problems may result in rich mixture and in engine turning off.

Check EGR and PCV valves. These parts may cause rough idle. When the problem is EGR or PCV you usually get troubles also when driving.

1993 nissian p/u run rich and it running real rough


If it is a carb engine have the air fuel mixture corrected by adjusting the screws on the carb. Try also adjusting the idling.

For EFI engines see if you can check the Idle Control Solenoid Valve, have it cleaned. You can also check the oxygen sensor if it is working or not

My 1998 Olds 88 has been stalling and running rough.


Check and clean the IAC valve. Idle Control Valve. Use brake cleaner or carburater cleaner . Remove the duct work from the air filter assembly. It is located just inside . Run the engine at 1200 rpms and spray the valve. The valve can also be removed and cleaned.
