Well I'm glad to see Clare didn't call you stupid too, at least
indirectly, like she did when I asked a similar question ;-). (and I
always thought Canadians were nice people?? ha ha)
I think a good workshop manual will be your best reference. If you're
stuck with a P00172/4 diagnostic code, it's true that there may be
other reasons, including a dreaded TSB 03-16-1. Fortunately, the
cause for mine turned out to be crappy gas from WALMART (get what you
pay). A $2 bottle of STP gas conditioner fixed my problem but I would
still need to do the TSB sometime soon...bummer! Actually I'm now
thinking of just taking my POS to a ditch...

What initiated you to want to replace the O2 sensors on your Windstar? Need
more info.. mileage, codes (if you have any), and what prompted you to start
troubleshooting? CEL, rough idle, or some other symptom?
The check engine light is on, and when stopped at a red light the rpm's
low, and sometime the engine stalls. Ask a mechanic and he told
me that 9
chances out of ten the o2 sensor was gone. 128000km's. Problem
the engine was shampooed.
If the CEL is on, then you have HARD FAULTs, get the codes pulled and see
exactly what the computer is having a hard time with before you start
throwin expensive parts at this thing. Atleast give yourself a heads up.
Asking someone anymore what the problem might be without codes, is a crap
shoot. You can end up chasing your tail and putting hundreds of dollars into
a problem that isnt even close.
Your local auto parts store should be able to pull codes, or a small time
shop will sometimes do it for about $20.00. It takes 5min and you have a
better idea of what you need to trace down, and if you dont have an
explanation for the codes, post here and I will look them up for you, and
give you possible causes.
They put electronics on engines for a reason, not neccessarily to help
troubleshoot, but hey its a great side effect, why not take advantage of it?
My best guess is that you probably got water into a connector and caused a
problem.. Pull the codes..
What you need to do is get the codes read for the check engine light. I
think the warranty in the US for the emissions is 80,000 mi which is pretty
close to 128,000 km. You might still be covered under the waranty for this,
depending on where you live. So you need to find out what the computer is
What do they use for shampoo? Johnson and Johnson's? Or Pert Plus? Did they
Seriously, these "shampoos" aren't really good for the engines. Apparently,
you either got some of the soap inside the engine or it affected the
electrical connections to the O2 sensor or something else. Apparently, part
of the shampoo is the engine wash with a pressure washer. Maybe they got
water where they shouldn't.
It could also be hard to find.
You should ask the shampoo place. IF they messed it up, they should fix it.
Just don't let them cut hair.
