1998 Ford Windstar 6 cyl Front Wheel Drive Automatic 106000 miles
Hello, Car has 3.8L California car. Engine check light coming on driving issues have been rough idle light will some times go out on own. Codes read: P1537 & 38 IMRC open bank 1 & 2 & P0174syst. Lean.
Checked IMRC valves on lower intake man. Removed vac. Tube and placed test vac. Line and applied vac. No valve movement. With tube off finger on valve vac. Tube nipple moved valve manually little resistance either way. Replaced all 4 HO2 sensors both post were black, question what harm if I do not replace these IMRC valves ASAP other than bad fuel millage, & whats your opinion if I replace units with salvage yard units. Also what other issues in the emissions systems should I be looking at. To get this wonderful care running better with out spending $1000
