I'm experiencing some sort of sticking when slowing down after cruising. When I come to a stop the engine is running at about 1200 rpm. I shift into neutral and bump the accelerator and it goes back to the normal 800 (or so) rpm range. It won't do it driving around town, only after cruising. I have the recall throttle cable with the housing. I don't think it's the throttle cable, but I don't know. I haven't checked the service manual yet to see how the cruise works on this rig. What is most likely my problem? Thanks.
