Thank you guys...It does need the key cylinder assembly replaced, it is pretty worn, loose and sometimes doesn't go to the reset position clearly at all, and I have to monkey with it to get it to turn...I did the cylinder in a dodge and in a gm,,,is the ford just as easy???
And, that chime module must have something to do with the continuity for CE light, cause it has not gone on in 15 starts, drivings and stops/turn off...and it was on every time I drove. I'm sure the O2 sensors didn't just fix themselves and whatever was giving me the other couple codes too.
I did notice that sometimes it didn't bong when I left the door open. All three girls do it. so next time, I'll try the steering column up/down wiggle and see if it stops. Again they all could really use a new assembly, but it sure is nice not listening to it and seeing the ce light on all the time. The previous owner put electrical tape in front of the light, but of course you can still//could still see it.
