SETTING THE IDLE
This is a simple but critical adjustment covered briefly in the Howell instructions that at first I did wrong because I did not under stand the sequence of the adjustments.
The computer adjusts the idle depending upon RPM, throttle position, temperature and other conditions. The computer controls the idle using a small stepping motor that adjusts the idle air control. What this procedure does is to run the stepping motor to one end of its' travel and then you manually set the warm engine idle as a starting point to give the stepping motor enough range of control for all conditions.
The following setup procedure must be followed exactly: ( I did not understand this)
Warm up the engine
Turn off the key and stop the engine
Place the jumper between the A and B connections on the diagnostic connector.
Turn on the key but do not start the engine
(the stepping motor will now go all the way to one end of its' travel and you will be able to hear it clicking when it has reached the end)
Remove the four conductor cable from the idle air control stepping motor
(the stepping motor is now positioned and removing power will let it stay there during adjustment)
Start the engine
Adjust the idle speed screw located near the throttle control to set the low idle speed
( set the RPM so the warm engine will idle with out help , should be about 650 RPM)
Turn off the key and stop the engine
Replace the stepping motor connector and remove the jumper from the diagnostic connector
The engine should now start and run on idle under computer control. You should not have to help the computer make the engine idle and the engine should not stall when you remove your foot from the gas peddle. My engine idles at about 1000 RPM under open loop computer control.
