Because it is so random, what all do you suggest?
So far, it has only done it in the winter.
Its taken 4 months to come back, so what could it be?
I use cruise control 90% of my driving, so having it would be nice.
I suppose there is no real way to tell, Huh.
Thanks for the quick responses.
Speed has never killed anyone, suddenly becoming stationary... That's what gets you.

Had you been using cruise that day the car acted up?

Might want to check out the pump/vac line to it.

I did use cruise that day. But about 5 hours earlier mid-day.
Does cruise control need vacuum to work?
Wouldn't there likely be a fault in wherever the valve, or switch is?
