I changed my air intake and everything seems fine except I noticed my idle is below zero rpm now the car feels fine. Is the car not use to the normal amount of air it's getting now? It seems to be running fine but this caught my attention please help.

  • Hi Brian - welcome. Can you please edit your post to give us more info. For example, currently you say it is idling at below 0 rpm - which is not possible.

  • I changed the air intake because there was a crack. When I say the car is idle at 0rpm because the needle with clearly be below 0 but the engine feels totally fine not like it's about to turn off. I tried to relearn idle procedure but must be doing something wrong. Before I changed it the rpms at idle were normal. Anyone else know what todo

  • Your RPM is not 0. Your gauge in cluster has gone bad or the cluster is not receiving the required information.

I would recommend checking that you go through your engine bay and check that you didn't forget any plugs or connectors while installing the new intake. If your car is running then RPM's SHOULD be displayed, so it seems that the cars computer is just not receiving that information due to a disconnect or maybe a blown fuse.
