Irratic idling problem, not the typical one

Irratic idling problem, not the typical one
I have a b18b1 that have constant irratic idling during cold and warm engine operating temperature. I have replaced it with 3 different iacv, 2 map sensors, checked the vacuums, drained the coolant a couple times to make sure there is no air pocket or bubbles, replaced the throttle body and gasket. Am i missing something here that i forgot to do? I am in need of help badly, much thanks

What type of irratic idling? 1500 - 2000 or a stuck type idle, like a 2step?
Is there a vacuum leak or something? Did you replace the intake manifold too? Also is the manifold flange straight or warped? i would check those. Also try another ecu.

irratic idling anywhere from 0-3000 when cold and 1000-1500 when its warm. replaced teh vacuum hoses, only got 2, from the fuel regulator to the im and the big fat pvc hose to the im from the brake booster. ECU, i haven't tried yet, but will

try resetting your ecu.....and spary some carb cleaner around your intake mani and throttle body....if any of these are warped the carb cleaner will get sucked inside the motor and cause a rich condition making the motor bog....then you will know for sure

intake manifold was never pulled off
o2 sensor, no check engine light, so i assume it is str8
resetted the ecu a lot, probably will pick up carb cleaner today

i am probably going to replace it with another one i have laying around
injectors and fuel rail, i am using stock ones
yea, i have a chipped ecu, stock uberdata ls map

Re: (oxSLEEPERxo)
take it to a local shop and have them hook it up to a smoke machine if u have a vaccuum leak ull definately find it that way and it doesnt cost much

yea, it might be, going try a couple different obd1 ls ecu tomorrow
fitv, got none
pcv valve is in good, thanks for the suggestion
any help or comments are greatly appreciated
