The base idle screw is right where the air flow hose to the stepper attaches in front of the throttle body. The cap is on the top of the plenum. But if I were you I wouldn't mess with it -- that's likely not the reason you have no idle. Search these forums and the forums on www.d-90.com, also FAQs on d-90 for 'idle' or 'no idle' etc. You'll find a lot of data. If you do decide to mess with the base idle, measure the number of turns you either add or take off so you can put it back when you find the real issue. Doug W. |
