This happed on my car when it had the LS1 in it. What I had was a faulty TPS sensor. To figure this out, I would go pull the plug from the TPS as it was running and then plug it back in and the RPMs would drop back down to the 1000 mark. I changed the sensor out and didn't have anymore problems after that.
It may not be the cause of your issue, but its just something to look at.

Thanks, that was another thing I was wondering about but didn't know if it could be it, but now that you mention it, I pulled the tps from a 76mm 4.3L throttle body, that may be an issue but I think they are the same sensor but still that one may be bad, thanks

Oops, never looked at it, thought you had to put a title so I always just hit a dot to be quick, but really, it doesn't matter..
