Hi. I'm trying to figure out what's wrong with my 1997 ford taurus
(automatic) with ~57,000 miles on it.
It intermittently stalls/idles out when coming to a stop, when driving
normally, when going around curves, when putting it in reverse or
drive, and sometimes even when I just turn the car on. When it does it
driving normally, it just seems to lose acceleration and I can mash the
pedal to the floor. The rpms go up slightly, and sometimes I can hold
the pedal down or keep pressing on it and it will kick back in, but I
usually have to slow down and it just idles out, and I have to restart
it. I have noticed, though, that if it's doing this, I can switch it
into 1st (gear?) position and it will kick itself back in. Does this
sound like a tranny problem?
I have gotten the throttle body cleaned, the throttle position sensor
replaced, the idle air control valve replaced, fuel filter replaced,
and the spark plugs & spark plug wires replaced. Still, the problem
I have called around to multiple technicians and one said it could be
the fuel pressure regulator or the EGR valve/sensor or the EGR intake
manifold needs to be cleaned. Another technician said it could be the
torque converter locking up. The service engine light only comes on
when it stalls out, but it goes away when I start the car back up. I
have had it tested at autozone with their code reader and they could
not find a code. It even stalled AT the autozone and the light came on,
and I had it tested while it was still on. Their reader found nothing.
Is it a problem with their reader, perhaps?
Also, I have never had the tranny serviced before. I was told it needed
to be serviced at 35,000 miles. I did once have a problem with the
transmission that seemed to go away on its own. It was leaking fluid
and I would usually have to add a quart or two every now and then to
keep the level up. Eventually, it just stopped leaking. I figured this
might count as a tranny flush, but I was told by a mechanic that I was
wrong about that, and it still needed to be serviced.
I'm getting tired of throwing away money into the car and would like to
see if anybody has any experience with this same problem or any
opinions. Anything you could contribute to help me out would be
