Idle Speed Adjustment '90 300ZX

Can anyone give me the procedure to adjust the idle speed on my '90 300ZX?

Thanks for any help,

Use a flat head screw driver to ajust

There is a idle air valve that can be variably opened and closed by turning a flat head screw on the back of the driver's side of the intake manifold. It may be hard to see but it's there (it's facing the driver side front wheel). Let me know if that helped cuz there could be a whole bunch more to it if that doesn't fix the problem. Cheers!

Thank you... I'll give that a try. I know what you mean about other things... these Z's have more sensors and electronic controls than the space shuttle. You gotta to be a rocket scientist to fix 'em.

I had to take my car back twice to Coleman Taylor and it took them 3 weeks to fix my transmission.

Thanks again,

Well that did it... she's idling nice and slow now. I remember seeing the screw before but I didn't know what it's function was.

The Japanese sure are good at hiding things.

Thanks Guys,
