Do secondary butterflies open when motor is reved in neutral?
Someone said they do. Another said they don't.
The car is a 93 Cx with a 98 GSR motor (usdm) / stock OBD1 p72 ECU. I had my father get the rpm's up to about 7k and they did not open. Before I start cutting wires I would like to know if they open in neutral or only when the car is in gear.
Thanks for any help!
I only ran 4 wires with my swap:
--A4 vtec Solenoid
--A17 Secondary Intake Solenoid
--D3 Knock Sensor
--D6 vtec Oil Pressure Switch
