I will have to look at mine as well, same year, same problem Thanks guys

Let us know the outcome on this for the next guys that have the same problem.

My cruse control will engage and the light comes on but it will start to speed up and then go wide open throttle. any one have any ideas. The only codes I have had is the po216 after I lost my lift pump. Is it possible that the injection pump and the cruse are tied together?

I have the warning light now...

Mine ended up being a ECM problem. Sold it. Never got it fixed.

Mine has the same problem but was able to get it to pop on once for about a minute after i had been messing with my brake switch. My abs light and brake light are on as well. My buddy mentioned I think on some fords if your brake or brake/ABS light are on the cruise will not engage. Is this the case here as well? I know the guy I got it from replaced the front hubs and they are ABS hubs as well but I dont know the brand he used as i have read this can make a difference. Haven't tried much but was curious as to your guys thoughts on this.

I would check the wiring from the abs sensor on the rear diff.. Make sure they ain't broke or something
