its very easy to adjust the cable connected to the cruise controll solenoid thing(I'm ASSuming its the same as gn's, and pretty much all other gm vehicles). try making the wire a little longer so it won't pull on it so hard. as long as you don't like crusing at 120 then it shouldn't have any affects on operation.
Mine doesn't like to pull up to speed very quick. if, lets say i'm crusing at 65, hit the brakes go down to 50 and then hit resume it takes forever to get back up to 65. now that i read this i thought about it, and i'll shorten mine.
just look at and you'll see how to do it.
