2002 windstar sel - 8/16/2006 1:27:10 PM    coucci   Posts: 3 Score: 0 Joined: 8/16/2006 Status: offline Hey there. I have a problem that i just cant figure out. 2002 windstar sel the engine light keeps coming on. i bought a code reading and it keeps coming up as p0402. I tried unplugging the vacuum to the egr and driving the van for a bit and the lite does not go off. Every once in a while the ligt will go off and on usually around the time my wife fills up, dont know if that is just a coincidence or not. Just wondering if anyone has any ideas. Thanks Mike Post #: 1

Does it run rough? _____________________________ 94 4x4 ranger (in reply to coucci) Post #: 2

I would also buy a new EGR gasket a 1 can of gumout. Remove the EGR valve and spray gumout in the passages. Scrape and clean old gasket. Replace gasket then replace the egr. Then disconnect the battery for 5 minutes to clear the code. _____________________________ 94 4x4 ranger (in reply to coucci) Post #: 6
