The car drives good, but once you come to a stop it idles like it wants to shut off;
worse with a/c on. I have changed the IAC sensor and most sensosrs on the Intake manifond , cleaned the Manifold as well as trottlebody.
I have changed the PCV valve as well.
I am out of ideas now.
Any suggestions?
1996 JDM ITR b18cR.
Engine was recently rebuilt but had the same problem before it
was overauled.
All suggestions welcomed.

 

could also be coolant related since idle is related to coolant temp. Check for bubbles, contamination, ect ect.

 

Have you done compression or leakdown tests?

 

bleed the coolant... if no bleader then change it right out... i did that and also put on Hondata Intake manifold gasket and my car idles alot better now
