Friday, June 13, 2003 - 08:35 pm yup. Here's the summary straight from the gnttype.org website:
1. Ground ALDL diagnostic lead (short the top two rightmost pins in the ALDL connector). 2. Turn on the ignition (but don't start the car). 3. Wait 30 seconds. 4. Leave ignition on and disconnect the IAC connector. 5. Remove the grounding from the ALDL connector. 6. Start the car. The car will probably run rough and may stall. Just restart and try again. 7. Adjust the throttle stop screw to set the idle to 500 RPM +/- 50 RPM. 8. Turn the car off and reconnect the IAC connector. 9. Turn ignition on and adjust TPS to proper settings. (.42-.44 at idle is typical) 10. Repeat procedure until the 500 RPM +/- 50 RPM in step 7 can be maintained while TPS is at proper idle setting.
