2006 ford taurus idles rough

I have a 2006 ford Taurus that idles rough. i have replaced all 4 oxygen sensors and all 6 spark plugs. i did not right down the all of the codes. there was a lot of them. some of the descriptions were pointing to the o2 sensors. They also stated the plugs were misfiring. like most other people, when you have the car in motion, there are no issues. i am waiting for the check engine light to come back on so i can get all of the codes. i have heard of the em-famous hissing sound coming from under the hood. could this be the hose that goes to the egr valve or the pcv valve?

If your having missfires I'd check the coils for sure and if you dont have a coil for each cylinder you should check the wires also.

SOURCE: PCV valve? IAC valve? Sparkplug wire? Throttle body? Vacuum hose?

the most common causes are plug wire, plug, vacuum leak at intake, fuel injector failure and last no/low cylinder compressio.

SOURCE: I have a 1999 oldsmobile

fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck

Replace the PVC valve, it's probably clogged.

SOURCE: My 2002 Ford Taurus will shutter and die when

the idle air control valve is responsible for engine idle.
this is a common failure on ford's. but I don't think yours is bad because it does idle high befor it dies.
you stated you had codes p0171 and p0174 these are lean codes for bank one and two, you said you found a vacuum leak and repaired it, the vacuum leak was mostly likely the cause of the lean codes, however the pcm has calibrated the fueling stategy for this lean mixture, what you need to do is erase the KAM "keep alive memory" this is done by unhooking the negative battery cable for 60 seconds, this is the only way to erase the KAM the $6000.00 machine I use wont even do it.

once the KAM is clean the computer will go into a relearn state and all operating values will be adjusted for the vehicles current condition, during this relearn session the vehicle may have some driveability issues (low or high idle, stalling, poor fuel economy) the relearn should complete within 10 minutes of idling and then 10 minutes of driving.

good luck and keep me updated

SOURCE: My 2004 Ford Expedition 4.6l has a rough idle and

well i'm sorry that you got the miss information here on fixya. because all internal combustion engines need a pcv valve to operate properly.

now the information you got first is correct and pcv valve can set false codes like o2's and lean bank conditions also can cause you vechile to run or idle rough.

no there are a few different styles pcv valves and some times don't look like your convetional pcv. some are heated in different ways either by coolant ( witch look like a conventioanl pcv but with a coolant tube around them) then electricaly heated and they don't look like them at all. but one thing that has to stay the same is the pcv valve has to ventilate the crank case and will be found somewhere on or near the valve cover because it is the easiest and most accessible point of the engines crank case area. so i would look for that and usally on that vechile it is on the passanger side valve cover in the middle.

with that said and seeing you did all those repairs i would go right for that as my next step. but there is other thing that cold cause this issue like leaky injectors and is almost more likely becuase of the o2 sensor code and backfire. do you have the code # so i can look it up and best assist you?

see vechiles are hard to fix over the computer as i am trying so if you have any more question/info about this issue please ask and i will be glad to help.

My 1999 Ford Taurus is ideling rough and dies, Could this be an oxygen sensor?


If it was an Oxygen sensor it would most likely cause the CHECK ENGINE LIGHT to come on.
I would check the spatk plugs and condition of the plug wires first.

1999 Ford Taurus 3.0L V6 24V DOHC Duratec Engine Engine was misfiring, plugs replaced, KAM erased, Idles Slow and Rough. OBDII says misfire ocurring on cyl 4 & 5. Codes P0300, P0304 and P0305


i would check the plug wires and the coils you check the plug wires for bad spots at night start the motor up and look at the plugs if you see a spark arch out the wire and to a peace of metal then the plug wires need to be replace.

Where is the EGR pressuure sensor at. Need to replace it.


Ford Taurus SES 3.0 L 6-cylinder
EGR valve are directly behind the intake manifold.

a1de76f.gif

I listen from Taurus owners that just had the same problem (EGR insufficient and EGR excessive) and they replaced the EGR valve and the 4 oxygen sensors (if you do this use Ford sensors). This didn't fix the problem; then changed the Vacuum Regulator Solenoid and a tube mounted sensor part numbers F63Z-9J459-AA, and 4U7Z-9J460-AA. this fixed my check engine light and code issues, as well as it stopped idling so high that it caused the trans to jump into gear. It sometimes jumped so hard that he thought he had a broken motor mount.

Good luck (remember rated this).
