Hi Aaron. With all due respect you need to stop changing parts and find out what the check engine code is. You're just guessing at what's wrong.

Get the codes read, they will point you in the right direction. There are too many things to list here all the potential causes without those codes. It could be the idle air controller, fuel pressure, clogged catalytic converter, etc., it could be a lot of things!

Most auto parts stores will read the codes for free, or you could pick up a basic code reader for as little as $50 - $60. Once you have the codes, post back here or look them up at http://www.check-engine-light.com

I know I had this same problem with my car three times actually and I had to keep getting the oxygen sensors changed. since there is more than one.

2003 Ford Explorer XLT Wants To Stall At Low Idle,, especially when at a stop light


How does it idle in park , does it run ruff or smooth? Are any lights lit on the dash , check engine etc. ? Could have a partially plugged IAC air passage .idle air control (IAC) valve ! The engine computer uses the IAC to control idle , when under a load such as when put into gear the computer raises the idle ! It does this by allowing more air to by pass the closed throttle into the engine raising the idle ! If these air passages clog they restrict the air flow an cause a idle problem ! Now if it runs ruff at idle in park you could have vacuum leak ! Rough Idle How to Fix Ford Taurus Engine Stalls at Stop Signs

I have a 98 ford taurus that stalls when idling?


check for vacuum leaks. clean idle air bypass passages on throttle body, they control air at idle needed to maintain idle speed.

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

2002 ford taurus with check engine code bank 1 and 2 lean. the car idles irratically and stalls.


You most likely have a big vacuum leak. PCV hose split or a bad Idle Air Control motor (IAC)

I have a 1995 ford taurus engine stalls when idling and smells of gas when accelerating it bucks. Changed fuel filter, could it be mass air flow sensor?


Start with smaller problems and check the fuel pressure regulator, the mass air flow sensor for these vehicles is pretty pricy. Is the check engine light on? If so, head to your nearest auto zone and have them check for trouble codes. If the check engine light isn't on, its not likely your mass air flow sensor

My 2002 Ford Taurus will shutter and die when running the air conditioner and sitting idle at a stop sign or stop light. When I turn on the air conditioner the rpms will fluctuate up high above 2 and then...


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

1998 ford taurus


It may be that you need the throttle body and air bypass idle speed control valve cleaned, this is easy to to, pull of the rubber air intake hose off the engine, hold the eng. at hi idle and spray an approved throttle body spray cleaner in, use at least half the can, then lower the idle and spray until the engine stalls, disconnect the battery for 5 minutes to clear any codes and reset "idle learn" system to base line in the Power Train Control Processor. Drive a few days to reset idle learn and this should cure the issue of stall, if not you may have another part failing.
