I just did a mini me swap on my crx and my idle is very high. <3k rpm>
info: 90 si crx,y8 head,d16a6 block,stock ecu,.stock intake manifold
I did not touch the intake manifold besides un bolting and new gasket.
The coolant has no bubbles .
the iacv is not dirty.
I have sprayed for vacuum leaks.
and the throttle cable was not moved in the process.
The idle stays at around 3k after it rises first to 3500 rpm. please help me .
