Re: Idle Speed When Stopped
 

Your computer controls the idle speed via information it gets from
the Throttle Position Sensor, passed on to the idle step motor. clean
their connections and variable resistor:

I think you got it, I disconnected and reconnected the TPS a few times
and the idle got a little smoother. It no longer dies out but it is
still a bit rough.

Engine off, ignition off:
open and close the throttle body (full open) several dozen times,
cleans the contacts a bit.

Engine off, ignition on:
slowly move the link on the trottle body from closed to full open
and back about five times, lets the computer adjust the sensor

Turn the ignition off.

Now see how it idles.

You should clean the idle air passage, that helps a lot.

Also check all the hoses. Spritz some TB cleaner on the hose
ends, if any is sucked in the engine will stammer.
