99 Windstar Codes
I have a 99 Windstar with check engine light on. Codes read p0401, 171, 0301 and 0303.
We've changed EGR, Plenum gaskets, isolator bolts, DPFE (only 0401 and 171 was showing then), checked all hoses, boots, etc and can't find any vacuum leaks. After changing all that the 0301 and 0303 codes came up.
My van is hesitating and has a slight backfire every now and then. When the EGR is plugged up it runs worse!! Any suggestions?
Thanks in advance, Ashlie
