| need all the following to be true (reference: [ http://z32.wikispaces.com/Throttle+Position+Sensor ] For your TPS to be set correctly, the following conditions must all be simultaneously true. The throttle bodies should be closed all the way. Removing the intake pipes allows you to see if they are completely closed. With the throttle closed, you should be able to see a port (one on each throttle) on the bottom of the throttle chamber. These ports lead to vacuum nipples on the undersides of the throttle chambers. If the butterfly valve is slightly open, it usually obscures the ports. The Throttle Sensor must read between 0.4v and 0.5v. The Hard Idle Switch should be "ON." There is a "sweet spot" found while rotating the TPS where the Hard Idle Switch will just turn on WHILE the Throttle Sensor reads between 0.4v and 0.5v. If this cannot be achieved, the sensor is bad and must be replaced.
