Usually a Lean condition will pop thru the air filter,when sitting at idle and you give it gas.When at cruzing speed it will shutter,feel like it's (the power)on and off.
Usually a rich condition will have poor throttle response,by very hesitant.When cruzing it will make deep low sounding noises,kinda sound's like blllump bluuump.

Correct me if I'm wrong.:2cents

It will also knock and ping when it is lean.

Will an afr of 15.8 cause it to knock and ping?
