Hey

I just reset the idel on my 93 EF because the idle was way out before after a friend touched the idle screw and messed it all up.

This is the procedure i followed:

Disconnected the battery for 30+ mins to reset ecu
disconnected ISC
started car (it wouldnt start)
bumped the idle screw up until car started and idled at around 750RPM

I then left the car to sit in N and D for a while ran the aircon and move the steering a bit and took it for a drive.

It is idling in N at around 900RPM and idling at around 700-750 in D

However when the car is in N and i put my foot on the accelerator and rev it and then let go of the pedal the revs drop and then randomly by itself go up again, hold for a little bit then drop down and settles to idle...

Is this the ECU learning or is there a problem somewhere????
Was the procedure i used to set the base idle correct???

Any help would be gr8
Thanx

Pretty much. Though you don't need to reset the ECU. Just disconnecting the ISC whilst doing your adjustments.

Doesn't hurt to reset the ECU once in a while though. Only it will need to re-learn everthing later.

Also if your running a standard cam thats idling a little fast, should be around 750 in N or P

My book says 650 +/- 25, try that see how you go.

it'll also depend on the car - adjust it until it feels right... mine has been slightly worked, so i need to have mine slightly higher than stock :wink:

The base idle is 750rpm in neutral/park with a/c off. Disconnecting the battery only erases the KAM. The best way to clean up the ECU is to erase old fault codes with the diagnostic plug. After about a week the KAM has re learnt but is back to the setting just before it was erased.
