Sorry, nonadjustable. Computer handles that.
You CAN"T, It is not ajustable. You need to check the idle speed control valve. Also check for a vacuum leak on the engine. If you don't find your problem here, then ask your question again.
yes they are in a 1994 chevy silverado and is located on the left side of the throttle body.
check for a vacuum leak.
While the truck is running in idle pull out the dip stick and read it.
I have 91 chevy k1500, It does this, Sometimes it will idle a few minutes, then jump to high idle and check engine light comes on, And sometimes its as soon as i start the engine... I was told it was a vacum leak, But im no mechanic
it has a low idle. Can also be a vacuum hose leak.
check the soleinoid
It should be idling at approximately 625 rpm while the engine is warm.
i would change the spark plug wires
idle should be aroung 900 iin park then when in gear should idle around 650 or 700
is the a/c on when this happens if so it could be the fast idle sensor
The IAT ( idle air temperature ) sensor is built in to the MAF ( mass air flow ) sensor.
