Question about 2002 Ford Taurus
Just started making a squeal noise, the noise will go away then come back, no pattern to it, just does it... when at a stop light or stop sign or just sitting and idle the car will turn off. The car turns back on no problem.. I was told by 1 mechanic it was not the belt, possibly transmission bolts???? Another mechanic said the flow to air filter clogging??
Let go with actually diagnosing the issue,
not speculation from a mechanic who says
a clogged air filter & if that was the case, doesn't
show you & install a new one with your permission
You own the car,wouldn't you know if the air filter
was in the car 3 or 4 years, Even them it wouldn't
be clogged & you should be checking & taking care
of that simple task yourself
I would say alternator bearings,water pump,drive accy
belt pulleys,have to go with common sense,what turns &
wears out & makes a noise
If the trans flywheel was loose you would loose the correct
cylinder recognition data from the crank sensor
Almost pays to just break down verse deal with todays mechanics

I had this problem once on an econoline van and it was the plantum gasket but before you change this check all the vacuum lines and get a digital volt meter and test the voltages on the mass air flow sensor and if you have to change the plantum gasket auto zone can print you out a diagram stating all you have to remove to replace it

yes on both accounts. you can by pass the compressor by getting a serpentine belt for a non air conditioned car.Why do you feel that the a/c compressor is the problem?

i have a 2001 ford taurus and it did the same thing a while back, call the dealer and ask them for the sensor that is behind the brake pedal. It is not the transmission .. cost less that 25 bucks to fix and takes about 20 min

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

ur oil pump may be failin-there r sensors everywhere on new cars-keepin u from starting as safety measure-computer systems r complex n things dont always show on 1 scan-they kinda hav the mindset of a pc
