[Gmecm] Re: Vortec L31 oscillating at idle

[Andrew Gibson]

The scan tool proceedure is in the functional tests menu. It has you start with the key on engine off, start the engine, then it initiates the learn commnad, and asks you to snap the throttle to get the engine up to the fuel cut out limiter. Then it's done. Takes about 30-45 seconds if your scan tool is capable. Mine is the Mac Mentor (OTC Genisis platform) Gm's OE scan tool of course should be able to do it.
