So i have a 94' del sol with a b20b4 block and 91' b16 head. its running off a chipped p06 running a "b20/vtec base map" by Ramey Built. The car idles very low to the point of stalling out regularly sometimes and if i turn on the AC it stalls everytime. Its throwing CEL 9

Things ive done to try to fix:
cleaned out IACV - I have one to replace it guna try that
replaced the CYP sensor - had spare guts so i replaced it -going to adjust gap

 

yeah, replace the sensor in the dizzy. but check the wiring first, since its easier. be sure to check under the pattery tray. ive seen loose trays cut the harness a few times, and the cyp sensor wires seen to be right on top in the OEM harness.

 

are you sure the sensor you replaced it with is good? have you tried changing the distributor with a known working one?

 

next thing im goin to do when u have time is bust out the multimeter and test wires and make sure all sensors have the right resistance
