throttle cable trouble?

I'm having problems with high idle after my engine has warmed up and I stop at the first light.I see this is a comon topic.Some have replaced alot of stuff and still have the trouble.How many of you have throttle cable trouble out there that you either lubed or replaced the cable and it fixed the problem?

High idle is generally a vacuum issue rather than a mechanical issue.

What are the specs on your motor, carbed or FI? What type of carb? Has anything else been done to the car or motor?
