If you installed a mild cam in your Gen III LS engine ('97-'04) with electronic throttle control and can't seem to get your EFI system dialed in properly, here's a series of short videos that should help you get it sorted out. The videos are under 4 minutes each and it should take you less than 20 minutes to watch all of them front-to-back.  20 minutes to learn how to tune your engine's idle speed?  Yep.  Pretty cool stuff, so grab your popcorn and get crackin'!
