Do a google ''1998 Ford drive cycle''
If you hook a scanner to the DLC & monitor for the ''inc'' , the incomplete test needs tobe performed.

1) Only do the ''inc'' test portion of the drive cycle, so you can get your inpection passed.


Example - So many miles @ 35mph city
'' '' '' @ 65mph Highway

I ended up driving a mix of city, then hwy, for about 10 minutes each and passed just fine. After 4 bottles of Heet and one of injector cleaner, my check engine light went away....Yippeee..

I own a 2001 f150 and had a blinking airbag on the instrument panel . I followed the advice on this website , soldering a new 12 volt bulb purchased at Radio Shack and soldered by them for a total of $3 or $4 l. I now have a working airbag system again. Thanks to posters on this subject. I disconnected the positive post on my battery to reinstall. I don't know if necessary but couldn't hurt. The bulb initially went out and caused the airbag problem when I disconnected the airbag switch indicator to repair my ash tray / change drawer below it. It was enough to burn out the bulb.
