    There has been no check engine lights. Had it scanned too. The vehicle has 122,000 miles. Is there a way to test the idle air control valve? As I've replaced parts it would run well then next time mess up again.

    By running well it would be that day of repair. The next day there would be problems off and on again

Could be a dirty throttle body, vac leak, or a defective idle air control valve. The computer adjusts idle speed by controlling the amount of air entering the throttle body via the control valve.
Is the check engine light on ?

    You could unplug the valve when engine idle is above 1000 RPM. The check engine light will come on, but the valve would stay in place. If that takes care of the problem, the valve may be the problem. It has a small electric motor inside that opens and closes the valve.

    I will try that tomorrow. Thanks!

SOURCE: 96 Nissan Maxima continues to have engine light

I had a similar problem - took it into 'Nissan Professionals' and they changed everything you did as well, and had no luck. After 4 or 5 times working on it, they told me that it was a 'loose wire' that had to be re-soddered and then the problem was fixed. I don't know where the wire was, but they made it sound like it was in or around the fuse panel under the hood.
I hope this might shed some light on the problem.

Idles rough and rmps jump while driving.


You may want to have the throttle position sensor tested. You should be able to buy a Haynes or Chilton manual for directions. A new one TPS is only $60.00. Test before you replace.

Although is could be a fuel filter, it could also be a fouled spark plug, or a bad spark plug wire. Once you've ruled these things out, the problem could be the TPS (throttle position sensor). This controls your idling speed under all conditions. A faulty TPS will usually idle fine when the engine is cold but once warm, will tend to sputter and in some cases, stall.

Lumpy idle when starting it in the morning, but runs and idles fine once reaches normal engine tempature.


Possible leaking injector(s), leaking head gasket so there is water in a cylinder overnight, or coolant temp sensor reading colder than actual temperature, which would induce a flooded condition. Narrowing down the possibilities can be accomplished by asking these questions: Does the coolant level stay the same, or has it gone down? Is the check engine light ever on? How many miles are on the fuel filter, spark plugs and other regular maintainance items? Fuel is in high demand on a cold start(filter). More fuel easily shorts out a bad spark plug. Too much fuel floods an engine and causes it to run rough or die if it even starts(coolant sensor/leaking injector). Feel free to contact me with more info. Thank You.

1999 Ford Taurus mechanical problem


Hello,
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.

Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.

Good Luck !
