I got my H22 tuned with a Hondata s200. The idle is at 1000 which is higher then it was, I attempted to ajust the Air Idle by the throttle, and it lowered it ,but everytime the fan comes on to cool the car, the idle drops from 800 to 600 or lower.

I adjust it back to where it was and now when the fan comes on, it drops from 1000 down to 800 or lower. Even when I drive the car and quickly release the gas and put it in neutral, the idle drops and then goes back to 1000.

Is this related to tunning the Honda? or is it a timing problem or something. Would a light flywheel cause this problem?

Help would be appriciated.

 

i have the same problem, i know it's my flywheel for sure

 

Really? is your idle set at 1000?
