whyfeel Posted July 7, 2009 Share Posted July 7, 2009 I need to adjust my idle. It sits at 400-500 and I need it ~750. I've had a '79 FI throttle body on my last car and the idle adjustment was a screw directly on top of the throttle body at an angle. The Haynes manual states that this screw on top is how you adjust the idle. In my '82 I'm working on with stock FI components the throttle body does not have that screw on it. Pic 6968 is the throttle body from the side. Pic 6974 shows another adjustment screw on the side of the intake manifold that I don't know what does. If anyone knows, let me know please. 6970 shows a screw on the bottom of the throttle body that I think might be the one. Let me know what you think.

zcarnut Posted July 7, 2009 Share Posted July 7, 2009 The idle speed adjustment is the screw shown in the center of Pic #2. Quote Link to comment Share on other sites More sharing options...

zcarnut Posted July 7, 2009 Share Posted July 7, 2009 I think you mean pic #3? No, I did not. Read the factory service manual. The 1982-83 280ZX has the idle speed adjustment in a different location than the earlier 280ZX’s: Quote Link to comment Share on other sites More sharing options...
