This is the scoop. You have a primary throtle cable that runs at the fire wall and goes to the throttle body actuator *I think that's what it's called* Anyway then there will be a secondary throtle cable that runs off the fire wall and goes to a controller near the front of the engine bay. What happens (the easy fix) is that the line comes loose from the actuator at the cruise control (front of the engine bay) Just replace in the proper spot and tighten down. If that isn't the problem then it may be the acuator itself and in the 240 they use the vacuum type acutaor and there maybe a leak in the acutator itself and needs to be replaced($$$$<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt='

I had to get rid of mine for the SR along w/ AC so I know your pain. Long trips would absolutely suck if I didn't love the 240 so much
