Can the Idle Mixture be adjusted?

[78Z]

Hi all,

Can the Idle mixture be adjusted on the 280Z that does NOT have an oxygen sensor? On my car it says to adjust the idle mixture so that idle CO is 1% or lower. Does anyone know the procedure for doing this?

Thanks!

It can be done by adjusting the bypass screw in the AFM but you have to have some type of exhaust gas analizer to read the adjustments.
