Exclamation 1999-2003 Windstar p0171/p0174 trouble codes Technical Service Bulletin

MODS: before you move this i know the codes are already on a thread but i saw no direct info on the TSB

I know us commoners arent supposed to have access to these and I am too lazy to retype the whole thing but basically when you get these codes (which is as common as brushing your teeth on these) the TSB says do not replace PCM, MAF, or O2 sensors as these are not the root cause of the problem.....
these conditions are caused by a vacuum leak

1. Fuel Pressure Regulator vacuum line on the intake manifold end
2. Leaking Isolator Bolts in the lower to upper intake
3. Leaking Port gaskets in the lower to upper intake mounting area

or a combination of all three

if you want the whole bulletin i will be typing it up to add on here in a few days time if there is enough interest in it. It describes what needs to be done and replaced


BTW : I got the dealer to knock a hundred bucks off the price with this bulletin

I had a 99 windstar with the same codes. I bought an isolater bolt kit from the dealer, it came with the gaskets and all. spent 2-3 hours and a couple of beers later to fix and problem has not returned. been @ 6 months ago. good luck!

please can you. My wifes van just started with this and started with the fuel filter replaced it about a month ago. The codes have came back as of yesterday and now its surging and almost stalling at lights. I need to get this fixed and need to know the excat parts and even what i should be looking for but this sounds like the problem just need more detail on it.

Thanks

I am just coming across this myself, but I thought I'd share this with you as I think it may be helpful to me:

2000 Ford Windstar (Codes 171 and 174)
JLA FORUMS - 99 windstar [system too lean]

Let me know if you find it helpful. I have to decide whether I'm going to tackle this myself or pay someone to do it :(.
