You need to update your sig line!
It was obvious that the AFM on Sascha's 62 had been messed with - the silicone seal around the black cap had been removed as had the metal plug covering the air bypass screw. Simply putting the adjustments of that screw and the metering wheel back to settings similar to those on my truck was pretty much all it took to get Dino emissions legal. Amazingly, 23 year old OEM catalytic convertors hadn't been ruined by a year's worth of running extremely rich. There is, no surprise, something to be said for OEM Toyota-spec'ed parts!
