need help with my stalling 90 civic TX
 

Hi
I am looking for ideas on my 90 civic, it has a 1500 cc engine with the two port throttle body injector.
It works fine when cold but when it is fully warmed up it will not idle well and stalls all the time.
Things I have checked, vacum hoses, wiring connectors, codes (none).
I think it might be some kind of vacume leak, do the EACV give issue on these cars? I have a vacum diagram and a few other parts could be suspect, PVC, Map?

Any help would be aprecited, its my daughters car and she is getting tired of having to rev it at stops to keep it going, John

idle control valve

Does that TB have a BISS on it? If so, check to see it's either been loosened, or is missing.
