You need to make absolutely certain that the throttle plates are closed before you start her again.

And don't redline that rebuild again, it might ruin it if it hasn't already.

 

Stock ecu? AFM is hooked up?

 

everything its hook up so i really dont know what its happening

 

Make sure your fuel lines are on correct..if they arnt it will rev when it fires..on my FD i had them flipped and when i started it, it went up to 5k..take a look
