2003 Ford Windstar Repair Question
Asked on December 27, 2011
How to find a vaccum leak on a Ford Windstar 3.8?
I have a Ford Windstar and it keeps on showing the trouble codes p0171 and p0174. When I checked the van, I noticed that I could pull the PCV hose out without any resistance and also that rubber grommet was soaked in oil. I shaked the PCV valve and it rattled. Also when you are driving the van it hesitates when you hit the gas and sometimes at a stop it feels like it wants to choke out and die.

ford makes a kit for the pcv, hose and fittings. it includes the valve cover as well.
as far as the codes, it could be vacuum leak, maf sensor, fuel pressure or pcv. a shop with a scan tool can monitor long term trims and use a smoke machine to find the source of any vacuum leak.
