Sounds like you may have a vacuum leak, that can cause a very high idle on this engine and also cause a dying problem. I would check the IAC counts, if they are near zero, then you have a vacuum leak, look at the Throttle Body Base gasket, they are a common failure.

they, some of the mechanics, the master say it's a vaccuum leak at the trottle body base. I would chechk around the throttle body for a leak.
