Intake manifold idle jump helpp
 

I just finished my z1 intake plenum manifold, and inset everything back up and when i turn on the car it just keeps reving itself. I unplugged the abttery and still. It keeps reving to 2.5k-3k. And drops then redoes it. Anyone can help?

I think maybe the throttle bodies are on to tight?

Double check the wiring and hoses. Something is crossed.

Check to make sure all of your vacuum and fresh air lines are connected. I would start there.

Also, did you make sure to reinstall the intake gasket and throttle body gaskets?

Yea i solved it, it was the nissan engine cover has a bolt in the middle thati i thought was just to hold the cover but its a vacuum seal and that was what was causing the idke problem i has to undo the whole manifold twice for such a dunb issue that was right in my face

Thanks guys
