Operation without the secondary throttle control system:

The control of the secondary throttle system can be removed. With this modification the engine idles on the primary fuel injectors and runs on the primary and secondary fuel injectors when the throttle position reaches 1%. Normally there is no noticeable effect on drivability. All of the secondary throttle system parts can be removed except for the diagnostic sensor. Remove the vacuum hose from the sensor and leave the sensor port exposed to the atmosphere. This is a good alternative when secondary throttle system repair parts are not available. $200.
