03 Windstar P0171-P0174 codes
Hello all,
Hope someone might be able to give a little guidance, I have an 03 Windstar with 92,000 miles - recently diagnosed with P0171 and P0174 codes. Fuel filter has been changed, MAf sensor sprayed with cleaner, hose between fuel pressure regulator and manifold seems fine, I am thinking of changing the isolator bolts next---I see all over the web that they are a likely culprit?
Don't want to spend $$$ in and out of the shop. Any other smaller fixes I can try before tackling the iso bolts?
By the way, I am deleting the codes by disconnecting the battery, that won't hurt anything will it?
ANY HELP would be appreciated - thanks!
Matt

try the 3.8L engine forum
https://www.ford-trucks.com/forums/forum50/
different beast from our 3.0L and 4.0L's
disconnecting batt. neg. lead after each major change/service of fuel/air, emissions, engine operation parameter components is necessary to clear KAM in PCM so new unique adaptable parameters are learned by the PCM to match the component changes....
can use an OBDII scanner to clear codes but does not reset KAM.....so engine make perform poorly running on previous stored KAM settings

Thanks for the info - I don't have a scanner but have the codes from the first shop visit. So I will use the disconnect trick as I trial and error my way through this...
Anyone had this model year with this problem??

Not to step on anyones toes, but are there any Windstar years that don't have problems? Try cleaning the injectors by running Techron concentrate through a coupe tanks of gas and see what happens.

P0171 and P0174 on Windstar usually caused by bad upper intake gaskets. Not hard to replace at all. Couple hours of your time if you haven't don them before. Need to remove wiper arms and plastic cowl then unbolt all the bolts under plastic cowl to let metal part of cowl to lift upward so intake will slide out. Very simple actually.
