The Throttle screw is located on the throttle (obiously) its in a clinderical shaped channel located on the throttle just oposite or obliquely opposite the the throttle body position sensor. In some mazda vehicles (IN TRINIDAD) you need to loosen the throttle body position sensor and slightle adjust it eighter to the right or left to tuen the idle (For electronic controlled axcelleration) in some cases it can be adjusted via an ODB2 diagnostic tool (only in some vehicles that has electronic controlled axcelleration)

You can tell what type your vehicle is by looking for an axcelleration cable connected to the throttle body. If the throttle body has a cable it isnt electronically controlled and has an idling screw. If there is no cable but wires to the position sensor its electronic.

Would throttle positioning sensor cause my 1987 bmw 325e to idle up high?


Usually it is a sticking throttle plate, vac leak, or a problem with the idle control valve.

Where is the vacuum modulator on a 1989 Chevy silverado 4x4?


Have you tried to adjust the idle itself to bring it down? The adjustment should be right on the throttle body where the gas pedal is connected to the throttle body. There should be a screw that will allow you to adjust the idle up or down. If you loosen the screw it will take your idle down

Idles high


Idle speed is not related to the clutch position. With the pedal depressed, the engine is freewheeling and is not engaged with the remainder of the driveline. Likely the idle speed is the same with the engine running in neutral or with the clutch depressed. check the idle air control and clean the throttle plate in the throttle body as well as checking the throttle cable for binding etc. If there is a small vacuum leak, that also can raise idle speed.
