Hey guys. Just bought a Civic with the D15B7 in it. The only thing that concerns me is how low the thing idles. I cleaned the throttle body, and blew out the fairly new K&N breather but it still idles around 450-600. It's generally pretty steady between there but I just don't like it.

Anybody run into this same issue? Just wondering if there's an easy fix.

Thanks!

 

follow the correct idle set up and relearn procedure - you can google it. involves unplugging the iac, disconnecting battery, and adjusting base idle.

also check ignition timing - google as well.

and you may also want to run a ground wire from your coolant housing to the battery negative - something like a 12 ga should work - these cars do have ground problems that will affect idle.

 

Please post in the correct section to receive adequate help.

 

Did you clean the IACV and FITV?

Have you replaced the PCV valve?

Any CEL codes?
