yeah but why do you want to mess with the idle spped adjustment? what does your car currently idle at?slicked25 said:Yes, they seem to be. I might try some idle adjusting later tonight if I can figure this out. Do you know anything about using the idle speed adjusting screw?
The rpm '87 300 n/t when the A/C is off is 900 and when on is 1100. I know it's not that much difference but it doesn't take for the gas to be on E.♣Zen31ZR♣ said:That A/C idler pulley has a habit of seizing up. The bearing in it is very tiny , and after a few years I'm not very surprised that it would be locked up. The extra drag would affect your idle rpm.
No, the nut shoudn't move, that part is ok. I thought the whole pulley was seized up, from the way you described it. As far as the idle goes, that is way way too high. The VG30 typically idles at 500-700 rpm (5-spd trans), I think the auto idles about 100 rpm higher in neutral.... It won't normally idle much higher when under load, the IAC should stabilize it at 500-700 rpm no matter what.slicked25 said:The rpm '87 300 n/t when the A/C is off is 900 and when on is 1100.

When I turn the A/C is on that compressor pulley works fine but the idler pulley bolt isn't moving. Can I put some WD 40 on it or loosen the nut?
