Default 91 ef hatch b20 obd1

Hi all. Been having a real pesky problem with my swap and havenot figured it out yet. Basically have poor idle, i mean crappy. It starts fine then bogs down real low, then stalls. Usually happens when it gets warm, If you give it gas it is fine. Usually run like crap after its warming up which makes me think its an air/fuel metering issue. Possibly after closed loop

smoke tested and brake clean cannot detect any vacuum leaks

iac was relearned
New tps and calibrated
new map sensor
cleaned iac
tried two different fitv
Fuel pressure is there
new spark plugs, wires cap rotor spark is present

Any help is good thanks for reading

Double check your mechanical timing and your ignition timing.

How about... Clean the throttle body if it's dirty. If that doesn't work mechanically open the throttle body a hair.
