Dashpot Adjustment (Turbo)

WARNING: This page is about a different car, the 1989 Mazda RX-7. However, it is still accessible from the selected car via links, so may be relevant.

Operate engine to normal operating temperature. Stop engine and remove intercooler. Disconnect throttle sensor connector.
Using ohmmeter, check resistance between terminals "A" and "B" of throttle sensor connector. See Fig 1 . Resistance should be 1800-3800 ohms when dashpot rod moves from throttle lever.
Loosen lock nut and adjust dashpot to obtain correct resistance reading. Reinstall throttle sensor connector and intercooler.
