I changed my SC:s IAC valve, and now car runs nice idle on P or N, but when I try to put gear on D (or any drive position) it stalls. If I unplug IAC, engine stalls too (normal, I quess). My car used to run very high idle and made that "honking" sound, so that's why I changed IAC. I bought new valve from local Ford dealer, and its model is Motorcraft CX-1826 (E9SZ-9F715-EA), so that should be right. Any ideas what's wrong?
