i got my jdm engine and it is installed, it also now has a fidanza flywheel rps clutch custom 3" exhaust and im wondering why it is idling wierd. it will start fine and it will begin to idle fromaround 1000 and then rev to 3000 by itself. if i try to rev it myself it cuts out. this is the first time ive started it and tried to run it since the new engine. any help would be great.
