I did the High Idle Mod and it worked great for about 2 mos. Then it worked intermittently. Now it doesn't work at all. I was thinking loose wire, so I traced it from where I hooked it to the green wire on the brake harness to the main harness in the engine compartment. Everything looks OK. Any ideas what else could be causing this. One thing I haven't done is try the Cruise Control. I just thought of that while writing this. I will try it on the way home and update tonight.

If cruise is working check to make sure the break switch isn't slightly pressed.

Cruise is working fine. Tested it on the way home.

Well, I found the problem. Bad connection on the brake wire tap. Fixed that and now I'm back in business.
