Did you try disconnecting the throttle cable to see if it is causing the throttle body to stick open?

air is coming in somewhere either through a large vacuum leak or through the throttle body not closing or a bad idle air control valve

I think it is a vacuum leak cause I ha a couple of te joining plastic piece for the lines break an I thought I fixed them. I am guessing the I just need I replace the connectors instead of try and fix as some would say redneck fixing.

You cannt make a oomplete gasket out of permatex. If you have a bad gasket it has to be replaced.
