I have a 96 Lx duratec and I recently had my check engine light come on. I had it scanned and the trouble code it gave me was that the IMRC is closed shut. the second code read that the oxygen sensor had a slow response. That is understood no problem. But as for the IMRC box do I need to buy a new box? maybe used? has anyone encountered this? Also is there somewhere I could buy it for cheap? Here Ford wants 300.00 cdn.
