Welcome to your first post on AF.
That is a hard one to answer.
Not knowing the engine an year and model and mileage and tune up history.
Code 171 and 174 are lean codes. But many things can cause the codes.
If the system is actualy running lean it needs to be checked out.
I would suggest you get it checked out buy a good repair shop that is trained in diagnostic work.
Even if a code is not set or light on it still could be running lean.
And if it has never been tuned up like fuel filter and plugs and so on now would be a good time to do so.

So I take it, this could have been jsut because we drove so far? We had driven over 400 miles straight before it went on...perhaps this was a factor??? I have grown not to trust the car- sometimes the interior lights come on for no reason... they will flash on, or even stay on for a long time- very strange!
Thanks for your help.

Is the TSB supposed to beat Ford's expense? Of course the light went back on and it's in the shop right now...it looks like it will need both the upper and lower Manifold gaskets replaced, etc, etc.... and will be pretty expensive. I am wondering- if this is a common problem and a TSB has been issued- why no recall?

MT-2500 · #22 01-26-2006, 01:24 PM

Tsb's are only factory service bullitions that are put out to make a tech/mechanic aware of certain problems.
They really do not fix anything only point you to the problem.
And they are a you pay. A recall and the dealer will pay.
But there is a lot of known problems out there and it is almost always you pay unless under warranty.
The intakes gaskets give a lot of problems on gm and ford both.
But most are still you pay.
However Ford had a class action law suite against them on the 4.6 engine and are paying on some intake problems.
So hang onto your repair orders and maybe some day they will pick up the bill.
But do not hold your breath on it.
Good luck

I figured as much. Why not just make a better car, right?! And why not make NEW parts to go in the cars that are better and will be compatable with the car?! I have already had the lower replaced once and am afraid to find out what both will cost me!

DRW1000 · #24 01-26-2006, 01:32 PM

Recalls are normally only done for safety (read liability) issues. Design flaws such as this are not recalled but the benefit is that there is a known procedure to correct the problem. I have heard of some being able to talk the dealer into absorbing some of the cost or having it covered under the emissions warranty.

BTW the tsd is only for the upper portion of the intake and inludes the Isolator bolts, the port seals, the vaccuum regulator hose, one valve cover (depending on the year).

The interior light issue may be realted to the door switches. Do a search under interior lights and I think you will find that the problem might be in the rear hatch switches

Have the same problems. Repalced the plugs, wires, PCV, EGR and fuel filter. Took it to teh Ford Dealership and they said i needed to replace the intake o-rings and clean the EGR ports. Also replace the DPFE sensor. Don't think it's worth the $100 taking it to a dealer

Do these codes (lean) cause bad fuel milage? I live in Ohio, and warm the van up in the morn. for 10-15 mins, (in winter) and drive mostly in town, and I'm only getting a little over 10 mpg...I know I need to fix the code problems, and while I'm at give it a tune up, but just wandering what kind of milage you guys are getting...1999 Windstar 3.8l

Hello

We have a 95 and the worst millage that we can remember is 15 mpg. The best is around 23 mpg. If it's cold we try to warm it up just like you for 10 to 15 mins.

Regards

Dan

I'm just getting the whole thing done- Neither my husband or I have any idea how to fix anything on crs (I can change the bulbs myslef, though, rather than pay someone $20 to di it!) I am having everything the TSB advises done at a cost of $1075.00. As soon as financially possible, though, this car is going bye-bye and I will trade it in! I don't want to spend another $1,000.00 next time it happens! Will look into all the advice given for the lights, thanks! Where will I find the rear hatch swithces? I know, silly question, but, like I said, I am not car-literate!

I would suggest you get it checked out by a good repair shop first. Many things besides what the TSB calls for can cause the codes.
Tune up end is first thing. Fuel filter ,low fuel pressure ,pcv valve,maf sensor and other sensors and even sometime the PCM needs a reflash.
Good Luck MT

Good advice from MT-2500. Exhaust other possibilities.

What year is your Windstar. The TSB only covers 99 to 03 models with the 3.8L engine.

If it does turn out that you need the TSB performed I would shop around. $1075 seems high to me. Was this at a Ford dealer? I also do not feel the valve cover is necessary (but that is just an opinion). I would think that the port seals and bolts can be purchased for about $100 and I would suggest that 4-5 hours labour should be plenty.
