air fuel ratio when downshifting?
i have been doing alot of search about the air fuel when accelerating,at idle,crusing,and boosting but what i have not found is what about downshifting or letting the motor slow the car down .. my guage always goes full lean then does this(--) im guessing it has to do with a fuel cut or something but what i want to know is this ok to happen since the car isnt under a load for it to be full lean like that...
