Engine revving wide open

I am currently working on my sisters 2000 model concorde 3.2L. I have changed both valve cover gaskets due to leaks. I also replaced upper intake gasket and throttle body gaskets in the process. I reassembled and attempted to start the engine when it revved wide open and i immediately had to shut it off. I disassembled and reassembled twice thinking i may have missed something but i am getting the same results. Please any advice would be greatly appreciated.

Are you sure the throttle isn't just stuck open? I've had that happen to me once.

That was my first thought but i checked that and even with the throttle cable disconnected it still does it. Im stumped. I thought maybe a vaccum leak but i checked for that too and can't find anything there either. Im begining to lead towards an electrial problem.

I mean... if the throttle is actually closed, for sure, how is it possible for it to revv "wide open"?? Unless, of course, the revving sucks the throttle open, but I thought that was impossible, with the big spring holding the throttle closed... is the spring broken or popped out of place?
