[QUOTE="decipha, post: 16241731, member: 74327"] all production vehicles idle at stoich its required for US federal emissions since its obvious you are confued on AFR you should use lambda as its significantly easier to understand stoich = 1.000 (what the 18 gt u seen was idling at roughly 14.0 AFR) where as 14.0 AFR on your vehicle as you see it on your wideband is actually 0.95 lambda still 5% richer than stoich [/QUOTE]
