Randomly I started getting cel. Every time I read it. It’s showing p0172 ( system too rich bank1). So I started notice on how I drive my car and it appears only when I’m going over 4000 rpm when I’m shifting gears. Normally I drive like grandma on street. Rarely I get on it never redline it. What could cause on this? Is it a tune that needs to be looked at?
