We have some coils we can swap in. Also, unhook the AFM from the airbox and have someone push the cone in a little when you start the car. If that makes a drastic difference, we might have found a winner. I think you can also unplug it altogether, and if it idles, but doesn't rev, it's also bad.

Great suggestion, but he doesn't even need to go that far. Just remove the airbox lid, remove panel filter (assuming still all stock airbox & filter). Then he can reach in with a finger & move the AFM cone.

You don't want to move it all that much - if you push it too far in, the car should go pig rich & stall if it's idling.

An S5 won't run with the AFM unplugged; not sure if it will even start that way.
