My first guess would be either:
Your throttle plate isn't actually closing all the way...or
Your TPS sensor is bad, loose or needs to be adjusted.

Easiest way to check for leaks is to pressurize those pipes...which I would do for sure anyways. Its amazing what kind of small leaks can get patched up easily that you wouldn't have otherwise known about.

 

i figured it out a little one of the weld on the intake mani had a hairline crack i closed it up now it idles at 4k not 6k or 7k but its still really high... can this be a MAP related issue or even a dizzy problem... oh and the throttle plate i def closed.... i dont think the TPS is bad due to the fact it is fairly new and the is no engine codes.... thanx any more info would be appreciated!!
