Q: How to disconnect and reconnect the accelerator cable on Mercury Mariner?
A: This guide applies to 2008 and earlier models. Disconnect the cable from the negative battery terminal. For V6 models, remove the engine cover. Detach the accelerator cable from the air intake duct or intake manifold. Disengage the accelerator cable from the cable bracket and Throttle Body. Inside the car, disengage the lower end of the accelerator cable from the pedal. Pull the cable through the firewall, remove the grommet and pull the cable through the hole. Installation is the reverse of removal. Ensure the throttle valve moves smoothly. After reconnecting the battery, the PCM must relearn its idle and fuel trim strategy.
