Hondata

Hello i got a 2012 honda civic si with skunk2 exhaust, downpipe, rbc intake manifold, 3.5 prl cai, rdx injectors, throttle body adapter plate, zdx throttle body. My car is tuned but when im driving and i got to a complete stop my car idles from 1000rpm to 1400rpm then back to its normal idle that is 1000rpms. Does anyone know how can i fix this idle issue.

Thank you

This is more than likely due to having a larger throttle body from a different vehicle. You may want to read the following: https://www.hondata.com/forum/viewtopic.php?t=18527
