I'm reading the GM service manual before putting on my CAI-1st time working on a car... It says you have to do an idle learn procedure after disconnecting the battery (which the CAI instructions say to do.) I'm wondering how many of ya'll who've done your own intakes disconnected the battery and did the idle relearn thing. I'm also going to look over the manual some more, but are there any other things I need to do after reconnecting the battery? Is the relearn neccessary? It says "only on Delphi ECMs only". I have an 08 LS sedan 5 spd. Anybody know if it's a Delphi? Any tips and info are greatly appreciated!
