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.

Go over the entire motor top to bottom and make sure each and every sensor and plug is plugged in securely and properly. After you do that, make sure your AFM is plugged in :)

Once you confirm all that, then make sure the TPS is calibrated correctly and that you have a good operating ISC valve. If you feel those are both ok, then check your codes. Come back and tell us what they are and we can go from there.
