So i notice when i first start the car in the day, my a/f reads dead rich like it suppose to on an autometer a/f gauge, because the o2 is not heated yet. But then it goes almost leans all the way out, to about the last 2 red bars. However after driving and i come to a stop, it almost always reads perfect stoich. My settings with SMC+ and DSM 450s is Idle:-32, 1k:-33. I smell a lot of gas, played around with the settings alot already, and can not seem to find a good working one. If i lean it out car stumbles, if i rich it more, it smells really bad. Any advice?
