Throttle sticking in cold weather S90-V90 1998

Am hoping Brickboarders can give me some advice on my V-90 w/ 116K miles. Here in Vermont, USA we have been experiencing some cold weather lately (-16F this morning).

Twice this week during cold spells the throttle has stuck while driving, acting like cruise control. Shifting into neutral sent the engine toward red line. Scary indeed, especially on slippery roads. I stopped, lifted the hood, manually operated the throttle cable, and manipulated the rubber boot which, I think, is related to cruise control. (Now you know I don't know what I'm talking about) This solved the problem until I got to work. I sprayed carbuerator cleaner on the butterfly, and some lubricant on the throttle cable / flywheel assembly, and didn't have a problem for two days, then it came back this morning.

I don't know if this is germane, but both times this happened after the car had been warmed up and driven about ten miles. The sticking started in exactly the same spot on my commute when I pass through a weird microclimate where the outside temperature can drop 10-12F over the course of a mile.

Your thoughts on the causes, remedy, and potential costs would be much appreciated. Thanks in advance for reading this far and your consideration.

    It very well could be a sticking throttle cable, but I would try and rule out the cruise control first. There is a servo module that has a vaccuum connection. You can try and disable that by pulling the vac line and plugging it. That and making sure that the throttle cable is free is where I would start. Good luck.

      THIS HAS HAPPENED TO ME THIS PAST, WEEK ALL I DID WAS MANUALLY MOVE THE LINKAGE AND IT FREED ITSELF UP , I THEN WENT TO THE GARAGE AND CLEANED AND LUBED THE MAIN THROTTLE HOUSING BUT NEVER THOUGHT ABOUT THE CABLE ITSELF . BUT DID WONDER HOW IT COULD HAPPEN BECAUSE THE THROTTLE IS SO WELL PROTECTED FROM THE ELEMENTS AND IS IN AN AREA WHERE THERE WOULD BE PLENTY OF HEAT, YOU ARE RIGHT ABOUT IT BEING UNSETTLING TO PUT THE CAR IN NEUTRAL AND IT REDLINES IT SEEMS OK NOW BUT IF YOU DISCOVER ANY THING MORE PLEASE POST AND I WILL AS WELL THANKS PETER
