I printed out the IAC/TPS Adjustment instructions from this site. It doesnt say when to remove the paper clip from the A-B terminals in the diagnostic.

And how do you know if the paper clip is making full contact? when the engine light comes on, with just the ignition turned on?


do you remove the paper clip before or after turning the engine on to perform the IAC test?

And this sites intrustions does not mention the timing wire being disconnected but i have been told to do so while performing this procedure.

can someone enlighten me before i screw up my ecm?


thanks
